Turkish authorities say that forty-one people have been killed and 239injured in a terrorist attack on Turkey’s largest airport, Istanbul Atatürk. The airport is Europe’s third busiest airport. The Turkish Ministry of Justice said that two terrorists blew themselves up outside the security checkpoint at the entry to the international terminal. A third terrorist blew himself up in the terminal’s parking lot. Recent months have seen an increase in terrorist attacks against Turkish civilians. These attacks have been carried out by both ISIS Islamists and PKK Kurdish separatists.

Judges in the United States, the United Kingdom, and Canada have ruled that witnesses may not wear the niqab, which covers everything but the eyes, when testifying, in part because they believe that it is necessary to see a person’s face to detect deception. Contrary to the opinions of these courts, it is easier to determine the truthfulness of a woman wearing a headscarf or even a veil that leaves only her eyes exposed than a woman wearing no head covering at all, according to new research.

Jordanian intelligence chiefs stole millions of dollars worth of weapons sent by the CIA to Jordan for Syrian rebels — and sold on the black market. Jordanian intelligence officers were able to steal the weapons because they had direct access to the cargo. These officers “regularly siphoned truckloads” of the arms, delivering only a tiny fraction of them to the moderate Syrian rebels. Experts say the stolen weapons ended up in the possession of criminal networks or ISIS sympathizers.

Can the obsession millennials have with smart technology be capitalized on as a weapon against terrorist propaganda? The U.S. Department of State thinks so, and has selected three teams of student finalists — chosen from fifty-six universities around the world — to its headquarters in Washington, D.C., next week for the “Peer-to-Peer: Challenging Extremism challenge.”

In a historic move, the Colombian government and Marxist FARC guerrilla movement have announced that they have reached a deal on a bilateral ceasefire — the last major step toward ending one of the world’s longest wars. The cease fire agreement will be signed on Thursday in Havana by President Juan Manuel Santos and FARC rebel leader Rodrigo Londono, better known by his nom de guerre Timochenko. The war between the Marxist FARC and successive Colombian governments began in 1964. It has claimed 220,000 lives and forced 6.6 million out of their homes. ”Un sueño que comienza a ser realidad,” tweeted Juan Manuel Santos, Colombia’s president.

On Thursday U.K. citizens will vote in a referendum on whether Britain should remain a member of the European Union or exit the EU (“Brexit”). The most recent polls show a slight advantage for the “Remain” campaign, but pollsters say the vote is too close to call. Some security experts have argued that British exit from the EU would weaken Britain’s – and Europe’s – capabilities in the fight against terrorism, but Thorsten Benner, the director of the Global Public Policy Institute (GPPi) in Berlin, disagrees. He argues that it is unlikely we will see a fundamental weakening of European security should U.K. voters choose to leave the European Union.

The number of incidents involving armed attackers (active shooter incidents) has been on the rise over recent years with attacks taking place around the world — from the United States to India, from Norway to France to Kenya. Control Risks says that its Active Shooter training helps increase awareness of the threat and, in the worst case scenario, how best they can protect themselves.

Wars and persecution have driven more people from their homes than at any time since the UN began keeping refugee records. A new, detailed study which tracks forced displacement worldwide found a total 65.3 million people were displaced at the end of 2015, compared to 59.5 million just twelve months earlier. The report found that, measured against the world’s population of 7.4 billion people, one in every 113 people globally is now either an asylum-seeker, internally displaced, or a refugee.

More than fifty U.S. diplomats have circulated an internal memo to fellow Department of State employees, criticizing the administration’s policies in Syria and calling for air strikes against President Bashar al-Assad’s government forces. The “dissent channel cable” was signed by fifty-one mid-to high-level State Department officials involved in advising on Syria policy. The document calls for “targeted military air strikes” against Assad’s government.
