The United Arab Emirates, a close US ally which has accepted Guantánamo detainees in the past, took the 12 Yemenis and three Afghan nationals, some of whom the US has held for 14 years. Six of the men had first received clearances for transfer in 2010.

It is the eighth such flood to occur in a little over 12 months. The extreme events have occurred in Oklahoma, Texas, South Carolina, West Virginia and Maryland – but in Louisiana storm conditions are considered to have been a once-every-1,000-year event. Disasters like Louisiana floods will worsen as planet warms, scientists warn Gays Against Guns activists begin campaign in New York The protest group formed in wake of Orlando nightclub shooting occupied the lobby of one of the largest corporate shareholders of gun company stock yesterday.

Gays Against Guns activists begin campaign with 'die-in' at BlackRock HQ Trump proposes 'extreme vetting' of immigrants and visitors The Republican nominee Donald Trump has proposed an ideological purity test to screen out immigrants with sympathies toward radical Islam, in a sharp escalation of what he claimed is a religious war with the west. As part of a foreign policy speech, Trump asserted the US should only accept immigrants who "share our values and respect our people", adding that "we cannot let this evil continue." Trump proposes 'extreme vetting' for immigrants who may support Isis In a new Long Read, Timothy Shenk explores how Trump, or Trumpism, is embedded in postwar conservative ideology. "Most conservative thinkers have forgotten or repressed this part of their history, which is why they are undergoing a collective nervous breakdown today. Like addicts the morning after a bender, they are baffled at the face they see in the mirror." The dark history of Donald Trump's rightwing revolt Milwaukee mayor declares curfew Milwaukee mayor Tom Barrett has declared a citywide 10pm curfew in an effort to quell violent unrest in the wake of a police shooting over the weekend. Unrest in the city began after a Milwaukee officer shot and killed 23-year-old Sylville Smith, a black man, after he allegedly pointed a stolen semi-automatic handgun at police. On Saturday night, six businesses were torched. Four officers were injured in the unrest Sunday.

Miller later said she dived across the hard, blue Olympic Stadium track without really knowing why she had done so. "I was thinking, 'Oh my gosh, I am lying on the ground right now'," she said. It was instinct, a reaction, a response to seeing Felix in her peripheral vision. "But, hey, I got a medal out of it," she said. In another spell-binding night of track and field, Kenya's David Rudisha, the world's greatest middle distance runner, blasted through to take gold in the 800m final. Meanwhile, British race walker Tom Bosworth and boyfriend Harry Dinley become the third couple to get engaged at the Games, as debate rages over the ethics of public proposals.

Others move between church basements, other people's couches and cheap motels where entire families cram into a single room. But however itinerant the students' homes lives may be, principal Cheryl Bickle's Community Transitional School in Portland offer a sense of continuity. "Our kids are pretty hardcore homeless – well their families are – and so this is a stable place," Bickle says.
