Five people were killed outside the UK parliament in March in a similar car and knife attack, and in May, a suicide bomber killed 22 people and wounded 116 at a music concert in Manchester. These incidents are among a string of terrorist attacks in Europe connected to or inspired by violent Islamist extremism, with many since 2014 linked to the Islamic State group (also known as ISIS or ISIL). (For more information, see CRS In Focus IF10561, Terrorism in Europe.)\nEuropean governments and the European Union (EU) have been alarmed by the rise of the Islamic State in Syria and Iraq and its reach into Europe. EU authorities estimate that up to 5,000 EU citizens have traveled abroad to join the Islamic State and other jihadist groups. U.S. officials view the November 2015 attacks in Paris (which killed 130 people) and the March 2016 bombings in Brussels (in which 32 people died) as indications of the Islamic State\u2019s capacity to direct attacks beyond Syria and Iraq. All of the identified Paris and Brussels assailants were European citizens; some fought in Syria and/or Iraq and may have been connected to a \u201cEuropean branch\u201d of the Islamic State.\nAt the same time, European authorities warn about the dangers of \u201clone wolf\u201d terrorists motivated by the Islamic State\u2019s media-savvy propaganda. Although the Islamic State frequently claims those responsible for such attacks are its \u201csoldiers,\u201d evidence suggesting a direct connection varies and is absent in some cases. As in several other attacks\u2014including those in Nice, France, and Berlin, Germany, in 2016, and in Stockholm, Sweden, earlier this year\u2014those responsible for the March and June attacks in London used vehicles as weapons, in line with Islamic State propaganda that encourages followers in Western countries to murder \u201cdisbelievers\u201d with any means available.\nThe Manchester bombing\u2014carried out by a young British citizen of Libyan descent\u2014has exacerbated concerns that the Islamic State could be seeking to direct attacks from Libya given the group\u2019s presence and activities there. The Manchester investigation remains underway, but press reports suggest that the attacker was in contact with Islamic State fighters in Libya. Media reports also link the perpetrator of the 2016 Berlin truck attack to the Islamic State in Libya.\nEuropean Responses and Challenges\nEurope has grappled with domestic and foreign terrorist groups for decades. Especially since 2001, European governments and the EU have devoted increased attention to combating terrorism through stronger law enforcement measures and enhanced antiterrorism legislation. \nFrance and the United Kingdom have been at the forefront of European efforts to counter Islamist militants and the foreign fighter phenomenon. Belgium, Germany, and many other European countries also have sought to increase surveillance, prohibit traveling abroad for terrorist purposes, and more aggressively tackle radicalization and extremist propaganda, especially on the Internet and social media. Following the June attacks in London, UK officials called on Internet and technology companies to do more to remove terrorism content from their sites.\nNevertheless, the recent terrorist attacks have highlighted shortcomings in national domestic security frameworks and EU-level information-sharing and border controls. For many European countries, monitoring a growing number of potential assailants has been challenging amid budgetary and manpower constraints. Despite being known to European security services, some assailants have easily moved around Europe by taking advantage of the Schengen system, which largely permits passport-free travel among most European countries. In other cases, the perpetrators of an attack had been identified by authorities in one EU country as posing a potential threat, but the information was not shared with counterparts in the countries where attacks ultimately occurred. \nThe EU has made some progress in addressing these security gaps. Measures include adopting EU-wide rules for the collection of airline passenger data and enhancing external border checks. However, improvements have often been slowed by national sovereignty concerns, law enforcement barriers to sharing sensitive information, and data privacy and civil liberty protections.\nThe uptick in terrorist activity and the fact that many perpetrators were European citizens has reinforced long-standing anxieties about the integration of Muslims in Europe. Several terrorist attacks in Germany in 2016 were carried out by refugees or asylum-seekers, and experts note that such individuals may be particularly vulnerable to violent extremist propaganda due to trauma and dislocation. European governments also have faced pressure to improve counter-radicalization efforts in prisons. At the same time, certain policies targeting Muslims (such as banning some forms of Islamic dress) could increase a sense of alienation and exacerbate the potential for radicalization.\nIssues for the United States\nSuccessive U.S. Administrations and many Members of Congress have long been concerned about terrorism in Europe and its implications for U.S. interests. One American was killed in the November 2015 Paris attacks, four in Brussels and three in Nice in 2016, and one at the UK parliament in March 2017. President Trump strongly condemned the latest attacks in Manchester and London, and he asserted that the attacks demonstrated the need for the Administration\u2019s proposed \u201ctravel ban\u201d on citizens from certain Muslim-majority countries.\nThe spate of terrorist attacks in Europe may prompt further congressional scrutiny of counterterrorism policies and initiatives to combat violent extremism. The U.S. Visa Waiver Program (VWP), which allows short-term, visa-free travel for citizens of most European countries, has been a key congressional focus. Despite measures enacted in late 2015 to strengthen the security of the VWP, some Members of Congress remain concerned that the program could allow Europeans connected with Islamist militants to enter the United States. \nMany Members of Congress support close U.S.-European counterterrorism cooperation and may be concerned that reported U.S. leaks related to the Manchester investigation could damage U.S.-UK intelligence relations. The attacks in Europe could also raise additional questions for Congress about U.S. efforts to counter the Islamic State in Syria, Iraq, and Libya.

Security experts view the November 13, 2015, attacks in Paris (which killed 130 people) and the March 22, 2016, bombings in Brussels (in which 32 people died) as indications that the Islamic State\u2019s capacity to direct large-scale, coordinated attacks elsewhere in the world, especially in Europe, has increased. Many of those identified as directly responsible for the Paris and Brussels attacks reportedly fought in Syria and were connected to a \u201cEuropean branch\u201d of the Islamic State. Some observers suggest that there could be many potential European recruits among the estimated 5,000 Europeans who have traveled to Syria and Iraq to join the Islamic State and other extremist groups.\nAt the same time, European officials remain concerned about the possibility of \u201clone wolf\u201d attacks carried out by individuals who have not traveled abroad to fight but have been inspired by Islamist propaganda to commit violence at home. Although the Islamic State has claimed that the perpetrator of the July 14, 2016, truck attack in Nice, France, was its \u201csoldier,\u201d authorities believe that the perpetrator was largely self-radicalized. At least 84 people died in this incident, including two Americans. The uptick in terrorist activity has reinforced long-standing anxieties about the integration of Muslims in Europe and the potential for radicalization among some segments of Europe\u2019s Muslim populations.\nTerrorism in Europe is not new, but these incidents are the latest in a string of attacks linked to Islamist extremism and to the brand of extremism practiced by the Islamic State and its followers. Many of the recent attacks have exposed weaknesses in European domestic security, intelligence sharing, and border controls. Some perpetrators appear to have taken advantage of the Schengen system, which largely permits individuals to travel among most European countries without passport checks. For example, the suspected ringleader of the November attacks in Paris may have repeatedly traveled back and forth between Europe and Syria, despite being known to European security services. Europe\u2019s migration and refugee crisis has also heightened fears that terrorists could slip into Europe more easily. At least two of the November 2015 Paris assailants may have entered Europe through Greece in early October by posing as refugees with fake Syrian passports (authorities have yet to confirm the attackers\u2019 true identities, and EU officials caution against linking refugees with terrorism).\nEuropean Responses and Challenges\nEuropean governments have employed various measures to combat Islamist terrorism and the foreign fighter phenomenon, including increasing surveillance, prohibiting travel, and arresting returning fighters and terrorism recruiters. Some countries have bolstered existing counterterrorism laws, especially to ensure that individuals who travel abroad for terrorist purposes may be prosecuted (as required by U.N. Security Council Resolution 2178 of September 2014). European officials are also working to more aggressively counter radicalization and extremist propaganda, especially via the Internet and social media. Some have called on U.S. technology companies to assist these efforts by preemptively removing terrorist content from their sites.\nFrance, which is home to Europe\u2019s largest Muslim population (about 5 million-6 million), has been at the forefront of European efforts to counter the threat posed by Islamist militants. Recent estimates indicate that up to 1,600 French nationals have traveled to fight in Syria and Iraq and roughly 2,000 people are involved in Muslim extremist cells in France. French counterterrorism policies are considered to be among the most stringent in Europe. In the past year, the government has imposed travel bans on individuals suspected of seeking terrorist training abroad, prohibited speech that encourages terrorism, and significantly enhanced the state\u2019s surveillance authorities. (For more information, see CRS Insight IN10301, France: Efforts to Counter Islamist Terrorism and the Islamic State.)\nBelgium has the highest number of foreign fighters per capita of any European country (possibly as many as 550 out of a total population of roughly 11 million) and what some describe as a \u201cwell-developed underground jihadist pipeline.\u201d Authorities have prosecuted terrorist recruiters, disrupted some terrorist plots, and sought to strengthen law enforcement capabilities and better tackle extremism. Belgian officials have also pledged to \u201cclean up Molenbeek,\u201d the Brussels district that is home to dozens of suspected Islamist militants.\nDespite some progress, European officials have encountered difficulties stopping individuals from leaving for Syria and Iraq. Monitoring a growing number of potential assailants amid budgetary and personnel constraints has also been challenging, and law enforcement and intelligence capacities vary across Europe. While Belgium\u2019s counterterrorism policies have been criticized as insufficient, even France\u2019s widely praised counterterrorism apparatus has struggled to prevent attacks. Some experts suggest that increasingly tough policies in France and elsewhere targeting Muslims could further alienate them, exacerbating the potential for radicalization. Critics argue that efforts to integrate Muslims in Belgium and France have been largely unsuccessful.\nAnalysts assert that more must be done at the EU level. The EU has sought to enhance information sharing among national and EU authorities, strengthen external border controls, and improve counter-radicalization efforts, particularly online and in prisons. However, implementation of some initiatives has been slowed by national sovereignty concerns, law enforcement barriers to sharing sensitive information, and civil liberty protections. In April 2016, the EU adopted a long-standing and controversial proposal for the EU-wide collection of airline Passenger Name Record (PNR) data. Critics contend that it will infringe too much on privacy rights and does not go far enough in ensuring that PNR data is meaningfully shared.\nIssues for the United States\nPresident Obama strongly condemned the latest terrorist attack in Nice and reasserted U.S. support for France. The spate of terrorist attacks in Europe may raise additional questions in Congress about U.S.-led military efforts to counter the Islamic State in Syria and Iraq. The attacks also may prompt further scrutiny of law enforcement measures against terrorism and U.S. initiatives to counter violent extremism, both at home and abroad. Some Members of Congress remain concerned that Europeans fighting with Islamist extremist groups could enter the United States under the U.S. Visa Waiver Program, which allows short-term, visa-free travel for citizens of most European countries (see CRS Report RL32221, Visa Waiver Program). U.S. policymakers underscore the importance of maintaining close U.S.-EU counterterrorism cooperation in light of the Islamist terrorist threat and the foreign fighter phenomenon (see CRS Report RS22030, U.S.-EU Cooperation Against Terrorism).", "type": "CRS Insight", "typeId": "INSIGHTS", "active": false, "formats": [ { "format": "HTML", "encoding": "utf-8", "url": "http://www.crs.gov/Reports/IN10209", "sha1": "a73a8683785fd1685f20aabdb1122e3a91a7c59e", "filename": "files/20160718_IN10209_a73a8683785fd1685f20aabdb1122e3a91a7c59e.html", "images": null } ], "topics": [] }, { "source": "University of North Texas Libraries Government Documents Department", "sourceLink": "https://digital.library.unt.edu/ark:/67531/metadc847692/", "id": "IN10209_2016Apr18", "date": "2016-04-18", "retrieved": "2016-06-02T05:26:07", "title": "European Security and Islamist Terrorism", "summary": "This report discusses the current security climate in Europe following recent incidences of terrorism.
