The German and French interior ministers discuss cooperation between the two countries in the war in terror. German Interior Minister Thomas de Maizière has encouraged Germans to share evidence of radicalization. He said that radicalization of potential terrorists takes places not only online, but also often begins in a person’s social sphere.

Citizens of the U.S. and the world were deeply shocked and saddened when a gunman shot and killed about fifty patrons at an Orlando nightclub this past weekend. While the shooter’s primary targets were the people enjoying an evening out, a secondary object of such incidents is typically tourism, with the aim of terrorizing a population so much that people don’t travel there, thereby harming the economy. An examination of how cities and other destinations react to shootings and other situations that negatively affect tourism reveals that there are several important lessons about what cities can do to assure tourists they can maintain their safety. Destinations that take a greater leadership role and provide accurate, relevant, and timely information to their visitors are more likely to win in this zero sum game. Those that are unorganized or silent are more likely to lose. Ultimately, tourists vote with their pocketbooks, and a destination’s relative safety may determine where they take their next trip.

U.S. law enforcement is looking into a new angle to the Orlando massacre: Mateen’s sexual orientation. The former wife and acquaintances of Omar Mateen, the gunman who killed forty-nine people in an Orlando club, have said he may have struggled with his sexual orientation. Mateeen had been a regular at the Pulse, and tried to pick up men on gay chats and gay dating apps. “We are working to understand what role anti-gay bigotry may have played in motivating this attack,” FBI director James Comey said, adding: “But we are highly confident that this killer was radicalized and at least in some part through the Internet.”

Security forces in Bangladesh have arrested 3,245 people in the last twenty-four hours as part of broad campaign to put an end to a wave of Islamist violence against minorities, human rights activists, and pro-democracy bloggers. The total number of Islamists, and those suspected of Islamist sympathies, arrested since the campaign began last Friday no stands at 8,192, according the Bangladesh government sources.

Omar Mir Seddique Mateen, a 29-year American citizen whose parents are from Afghanistan, entered a night club in Orlando, Florida, at about 2:00 a.m., armed with an AR-15 assault-rifle and a hand gun, and opened fire. He killed 49 people and injured 53 – the deadliest mass shooting in the history of the United States – before being killed by police officers who stormed the club. Until the shooting early Sunday, the most lethal mass shooting in the United States was the 2007 Virginia Tech rampage, in which 32 people were killed and 30 injured.

The gunman who killed dozens of people in Aurora, Sandy Hook, San Bernardino, and, yesterday, Orlando all used an AR-15 rifle. According to the National Rifle Association (NRA), the gun, which was designed by ArmaLite for the U.S. Army and originally produced by Colt in the 1960s, is the most popular rifle in the United States. Between 5 and 8.2 million assault-style rifles are privately owned by U.S. citizens, and 3.3 million of those were AR-15.

The United States had 78 mass shootings during that 30-year period. The highest number of mass shootings experienced outside the United States was in Germany – where seven shootings occurred. In the other twenty-four industrialized countries taken together, 41 mass shootings took place. In other words, the United States had nearly double the number of mass shootings than all other twenty-four industrialized countries combined in the same 30-year period.

Robert Hannigan, the director of GCHQ, the British equivalent of the U.S. NSA, has warned that terrorists and rogue states are gaining the technical capability to bring a major city to a standstill with the click of a button. He said that the risk to cities like London would significantly increase as more physical objects – cars, household appliances — are connected online in what is called the Internet of Things.

In the wake of two car bombings which killed seventeen people, Turkey announced it was temporarily suspending the sale of fertilizers containing nitrate. The terrorists in the two bombings used fertilizers to make the explosives – as did Timothy McVeigh twenty years ago.
