Iraqi Kurdish Peshmerga fighters drive trucks as they head to the Mosul dam on the Tigris river that they recaptured from Islamic State jihadists on August 17, 2014 near the northern Iraqi city of Mosul.  Peshmerga forces backed by US air strikes retook the country's largest dam, about 50 kilometres (30 miles) north of Mosul, that jihadist militants seized the previous week, officials said.
