The adoption of the Convention for the Prevention and Punishment of Terrorism by the League of Nations in 1937 marked the entrance of terrorism in the field of international law. The present-day international legal framework for the prevention and combatting of terrorism started in the 1960’s with the adoption of the 1963 Convention on Offences and certain other Acts committed on Board Aircraft. This framework now consists of various multilateral treaties and protocols relating to specific categories of terrorist acts as well as several regional conventions on international terrorism in general. However, a comprehensive multilateral convention on terrorism is still lacking. This is mainly due to the continuing lack of agreement within the United Nations on a common definition of international terrorism.

Systematic classification → Terrorism
The Peace Palace Library has a collection of over a million publications. Each week, about six hundred new titles are added to our collection: books, articles, documents, online publications, etc. On this page, access is provided to this week’s new titles on Terrorism and related subjects.As we are right in the middle of moving to a new library system, it is not yet possible to automatically collect new titles for this Research Guide.
Hale-Ross, S., Digital Privacy, Terrorism and Law Enforcement : The UK's Response to Terrorist Communication, London, Routledge, Taylor & Francis Group, 2019.View this title in our discovery service
This book examines the UK's response to terrorist communication. Its principle question asks, has individual privacy and collective security been successfully managed and balanced? The author begins by assessing several technologically-based problems facing British law enforcement agencies, including use of the Internet; the existence of `darknet'; untraceable Internet telephone calls and messages; smart encrypted device direct messaging applications; and commercially available encryption software. These problems are then related to the traceability and typecasting of potential terrorists, showing that law enforcement agencies are searching for needles in the ever-expanding haystacks. To this end, the book examines the bulk powers of digital surveillance introduced by the Investigatory Powers Act 2016. The book then moves on to assess whether these new powers and the new legislative safeguards introduced are compatible with international human rights standards.
The author creates a `digital rights criterion' from which to challenge the bulk surveillance powers against human rights norms. Lord Carlile of Berriew CBE QC in recommending this book notes this particular legal advancement, commenting that rightly so the author concludes the UK has fairly balanced individual privacy with collective security.
The book further analyses the potential impact on intelligence exchange between the EU and the UK, following Brexit. Using the US as a case study, the book shows that UK laws must remain within the ambit of EU law and the Court of Justice of the European Union's (CJEU's) jurisprudence, to maintain the effectiveness of the exchange. It addresses the topics with regard to terrorism and counterterrorism methods and will be of interest to researchers, academics, professionals, and students researching counterterrorism and digital electronic communications, international human rights, data protection, and international intelligence exchange.
Badde-Revue, M. and M. Ruffo de Calabre, Ethics in Counter-Terrorism, Leiden, Brill Nijhoff, 2018.European armed forces have frequently had to participate in counter-terrorist operations while abroad. For many, however, counter-terrorist operations in their home country are a relatively new phenomenon. Armed and uniformed soldiers can now be seen doing work which is, in some respects, comparable to that of the civilian security forces. What are the ethical implications of this phenomenon? To what extent does it change the relationship between the soldier and the democratic state? Do emerging technologies encroach on democratic freedoms? Does the phenomenon re-define the relationship between the police and the military? Under what conditions can soldiers be trained to achieve victory by force of arms, be used effectively in crowded city centres? Conversely, do we also risk over-militarising our police?
Bayefsky, A.F. and L.R. Blank, Incitement to terrorism, Leiden, Brill Nijhoff, 2018.Incitement to terrorism connects the dots between evil words and evil deeds. Hate precedes terror. History has already taught us that incitement to genocide and to crimes against humanity unchecked will inevitably bring devastation to humankind. Incitement is an affront to the dignity of its victims, and poses a dire threat to all people of good will. However, combating incitement to terrorism poses operational, constitutional and human rights challenges on many fronts, both domestically and internationally. What is incitement? Where should the line be drawn between protected speech and incitement that should be criminalized? Does war change the calculus of what are appropriate and lawful measures to contain and respond to such incitement? And, how does social media and the nature of communication and engagement in our virtual world change or complicate how we think about, and can respond to, incitement?
This compilation offers expert analysis on incitement to terrorism across these challenging issues and questions. The contributors bring expertise from a range of countries and operational experiences, providing an illuminating and thought-provoking examination of domestic and international law, comparative approaches, and emerging trends with respect to incitement to terrorism.

Targeted Killing of European Foreign Terrorist Fighters in Syria and Iraq
In recent years, a significant number of European nationals have travelled to Syria or Iraq to train and fight with terrorist groups such as the Islamic State (IS). This flow of foreign terrorist fighters (FTFs) has posed serious security concerns for Europe, in particular with regards to the threat posed by FTFs returning to Europe to carry out terrorist attacks. In this context, it appears that a number of States have resorted to targeted strikes against their citizens in Syria and Iraq.Read more
Are Syria and Iraq the Middle Eastern Bloodlands?
Deir az-Zor is a sleepy town on the banks of the Euphrates in the Syrian desert, and did not ring much of a bell for most non-Syrians. Except for Armenians. During the 1915 Armenian Genocide, the Ottoman government deported hundreds of thousands of Ottoman Armenians to Deir az-Zor, where they were left to die or were killed outright. A German diplomat who was stationed in that area wrote that the Armenians were “slaughtered like sheep”. To the casual observer this looked allegorical or even hyperbolical, in any case unreal, removed far away in geography, time, and culture. Until recent times, when ISIS videos surfaced online. And again the desert soil of Deir az-Zor shone red with blood, and once more the word ‘Deir az-Zor’ served as a symbol of bloodshed.Read more
The ‘US Travel Ban’ from an International Law Perspective
On January 27th, 2017, American President Donald Trump signed ‘Executive Order 13769’ titled Protecting the Nation from Foreign Terrorists Entry into the United States’. The purpose of this order is to place a limit on the number of refugees to be admitted into the United States in 2017. The order suspends the entry of foreign nationals from seven Muslim majority nations namely, Iran, Iraq, Libya, Somalia, Sudan, Syria and Yemen for a period of 90 days after which an updated list will be put in place. The order also indefinitely suspends nationals from Syria. This blog will briefly highlight the international legal implications.Read more
Aleppo, Ankara and Berlin: Atrocities, Violence and Terror
Humanitarian Crisis in Syria. In the eastern part of Aleppo, a Syrian city held by rebels, thousands of civilians were trapped. People were being executed in those parts of Aleppo that had been retaken by Assad forces. Recently the trapped residents that were stuck in a small area with no safe zones posted final “goodbye” messages, pictures and tweets on social media. They have thanked supporters, and questioned how the world allowed the situation in Aleppo to happen. The situation in Syria has been described as a “stain on the world’s collective conscience”.Read more
Preventing Bioterrorism, Risk and Legal Instruments
According to the U.S. Centers for Disease Control and Prevention a bioterrorism attack is the deliberate release of viruses, bacteria, toxins or other harmful agents used to cause illness or death in people, animals, or plants. In both the popular imagination and among lawmakers and national security experts, there exists the belief that with sufficient motivation and material resources, terrorist groups can produce bioweapons easily, cheaply, and successfully. Some scholars disagree. Legal measures offer no guarantee for preventing bioterrorism, but nonetheless affect bioterrorism. What are the legal instruments addressing prevention?Read more
Coalition against Islamic State: Too Many Obstacles?
After weeks of fighting, Islamic State succeeded in taking over the Iraqi city of Ramadi and it currently controls large parts of the al-Anbar province, which borders on Jordan, Syria and Saudi Arabia. Almost 25,000 residents have fled Ramadi. This week Islamic State also overran Syrian government troops to seize Palmyra (Homs province, Syria), home to the ruins of a 2,000-year-old city that was one of the most important cultural centers of the ancient world.The U.N. human rights office in Geneva said a third of Palmyra’s 200,000 residents may have fled the fighting in the past few days.Read more
Nuclear security: Dangers and Achievements
Nuclear security is generally accepted to mean “the prevention of, detection of, and response to, criminal or intentional unauthorized acts involving or directed at nuclear material, other radioactive material, associated facilities, or associated activities”. In short it is about preventing terrorists from acquiring radioactive material or attacking nuclear facilities. Since the terrorist attacks of 11 September 2001, nuclear security concerns have been heightened, but how real is the danger and what are the legal instruments to combat nuclear terrorism?Read more
Homeland, Zero Dark Thirty and Jack Bauer: Rendition, Torture and the Demise of American Values
The latest in a series of Hollywood productions which reopened a debate about torture and extraordinary rendition is Zero Dark Thirty. Real life variations of Hollywood-scenarios have been unfolding as the US government has engaged in a program of extraordinary rendition since the Clinton Administration and which became widespread under the Bush Administration following the September 11 terrorist attacks.This blog examines Obama’s policy towards torture and (extraordinary) rendition.Read more
Colombia: At Last Peace with the FARC?
Columbia’s fourth attempt at peace with the Revolutionary Forces of Colombia (FARC) started formally last month in Oslo and will continue the 15th of November in Havana, Cuba. The earlier attempts- starting in 1984, 1990 and 1998- to end one of Latin America’s longest and bloodiest armed conflict all failed. Why would the outcome of the peace talks this time be different?Read more
