Hungarian swimmer Katinka Hosszu propels herself underwater at a training session in Budapest, Hungary July 15, 2015. Before she became 2014 World Swimmer of the Year and the first to pass the $1 million mark in prize money, Hosszu nearly hung up her goggles, frustrated that she failed to win a medal at the 2012 London Olympics. Instead, she adjusted her thinking and challenged the Olympics-focused training cycle traditionally followed by the sport's top athletes. Olympic medals are no longer her ultimate goal, just one of several aspects to her schedule, she says. As she prepared for the world championships, which are currently taking place in Kazan, Russia, she already had in mind the autumn World Cup series as well. (Photo by Laszlo Balogh/Reuters)

Left-wing militants protect themselves as Turkish anti-riot police fires water cannon to disperse a demonstration in Istanbul's Gazi district, on July 26, 2015. Tensions across the country are high, with police routinely using water cannon to disperse nightly protests in Istanbul and other cities denouncing IS and the government's policies on Syria. Turkey has launched a two-pronged “anti-terror” cross-border offensive against Islamic State (IS) jihadists and Kurdistan Workers Party (PKK) militants after a wave of violence in the country, pounding their positions with air strikes and artillery. But the expansion of the campaign to include not just IS targets in Syria but PKK rebels in neighbouring northern Iraq – themselves bitterly opposed to the jihadists – has put in jeopardy a truce with the Kurdish militants that has largely held since 2013.
