The Israeli police, acting on a request by the FBI, has arrested a 19-year-old Israeli Jewish man on suspicion of making dozens of threats against Jewish organizations in the United States, and against airlines in the United States and other countries. The unnamed teen, who has a dual Israeli and U.S. citizenship, lives in the southern sea-side city of Ashkelon. The arrest was made after several waves of threats in the past two months against Jewish community centers (JCCs) and other Jewish organizations. The teen used advanced technology in an effort to mask the source of his calls and communications to synagogues, community centers, and public venues.

Martin McGuinness, 66, died on 21 March 2017. He suffered from amyloidosis, a rare disease which attacks the body’s vital organs. In 1998, Martin McGuinness, a former commander in the Irish Republican Army (IRA), joined Reverend Ian Paisley, the firebrand Protestant leader, to support and implement the Good Friday Agreement, which brought power sharing to the governing of Northern Ireland. Many nationalists accused Paisley of instigating the Troubles by orchestrating opposition to the civil rights movement. Many unionists refused to forgive McGuinness’s role in IRA violence. For victims of violence on either side of the conflict, the focus on the past is understandable, and it is also true that there were voices on both sides of the divide who, from the outset, consistently argued for a more peaceful way toward change in Northern Ireland. Ultimately, however, figures such as McGuinness and Paisley both helped lead more intransigent minds down that political path. As long as future generations are prepared to continue with the same endeavor, the most enduring legacy of the former firebrand preacher and the former IRA commander will be a peaceful, just, and democratic settlement in Ireland.

A new study takes a detailed, in-depth look at Islamism-inspired terrorism convictions and suicide attacks in the United Kingdom between 1998 and 2015, focusing on the offenders’ backgrounds and their activities as well as offense-specified data. The study finds that the threat to the United Kingdom remains from “home-grown” terrorism, and is heavily youth- and male-oriented, with British nationals prevalent among offenders. Although small, women’s involvement nearly trebled in recent years and is typically supportive of men involved in terrorist activity with whom they have a family or personal relationship. Analysis of offenders’ residence shows the primacy of London- and Birmingham-based individuals as well as higher than average relative deprivation and Muslim population at neighborhood level.

The decision by DHS to ban passengers, boarding U.S.-bound planes at ten airports in eight Muslim-majority countries, from carrying in electric or electronic devices larger than a cellphone into the cabin, is criticized by technology experts who say the new rules appear to be at odds with basic computer science. Another line of criticism suggests that the ban may have less to do with security and more to do with the Trump’s administration’s plan to play hard ball with countries subsidizing major industries in order to gain a competitive advantage over U.S. companies.

On Friday, the militant separatist group ETA has announced that, by early next month, it will completely disarm, and that from that point forward it will pursue its goal of an independent or autonomous Basque region by political means. Friday’s announcement comes six years after ETA renounced the use of violence. ETA was formed in 1959, and, in 1968, launched a campaign of violence against the Spanish state. ETA’s terror campaign, which ended in 2011, killed 829 Spanish politicians, policeman, military personnel, judges – but also a number of innocent bystanders – in bombings and shootings.

Two internal government reports appear to weaken the case the Trump administration has been making for the temporary travel ban. The implementation of the second version of the ban has been halted by judges in Hawaii and Maryland. The first report, prepared by DHS, found that most of the suspected or confirmed foreign-born terrorists probably became radicalized after they arrived in the United States, not before. The second report, based on data collected by the FBI, shows that most of the suspected or confirmed foreign-born terrorists had come from countries not among the six countries to which the travel ban would apply. The data in the two reports “points to the central question about the travel ban, which is, are you addressing the issues you need to address when it comes to the threat?” says one expert.

The strategy of using people’s need for healthcare against them by violently denying access sets a dangerous precedent that the global health community must urgently address, researchers say. As new estimates of death toll for health workers are published, experts say the deliberate and systematic attacks on the healthcare infrastructure in Syria – primarily by government forces – expose shortcomings in international responses to health needs in conflict.

Over the past year, Syria’s government has consistently exploited the United Nations aid delivery system, deliberately and illegally depriving millions of Syrians of critically needed humanitarian aid. In a new report, Access Denied, Physicians for Human Rights (PHR) said that Syrian authorities, by continuing to exert unilateral control over aid deliveries throughout 2016, effectively guaranteed the sustained suffering of civilians in besieged and hard-to-reach areas across the country.

The Trump administration as well as Republican lawmakers are seeking to introduce legislation that would designate the Muslim Brotherhood a Foreign Terrorist Organization (FTO). Many are questioning this move. The fact is that the Muslim Brotherhood has not been directly involved in any violent terror attacks in recent decades. Indeed, designating the Muslim Brotherhood as a Foreign Terrorist Organization could have the effect of limiting the opportunities for those Muslims who are attracted by the Muslim Brotherhood’s moderate agenda to engage in politics. It could even accelerate recruitment to terrorist outfits – a possibility that the Trump administration might seek to take into account.
