Comandos de Salvamento rescuers Maria Martinez (L) and Ana Chichilla attend to a wounded homeless man in San Salvador, El Salvador July 16, 2016. The man was attacked with a machete by suspected gang members. In 2015, El Salvador registered a record 103 homicides per 100,000 habitants, making it one of the most dangerous countries in the world outside a war zone. But for many young people who have few chances to distance themselves from rivalries between so-called maras in their schools and neighbourhoods, a civil-society organisation called the Comandos de Salvamento, or Rescue Corps, has been a refuge.

A worker at the Jabal Saraj cement factory poses for a photograph in Jabal Saraj, north of Kabul, Afghanistan April 19, 2016. In an area desperately short of industry and jobs, local workers hope that the relaunch of the plant in Jabal Saraj, built by Czech engineers in 1957 and closed down by the Taliban in 1995, can show that Afghanistan's shattered industry can climb back to its feet after decades of war and destruction. But the outdated state-owned plant some 75 kilometres outside Kabul also shows how far it has to go before that promise can be achieved and there are serious questions over whether it has a viable future unless a new, modern facility is built to replace it.
