Iraqi volunteers from the Yazidi sect gather at the Serimli military base, which is controlled by the Kurdish People's Protection Units (YPG), in Qamishli, northeastern Syria on the border with Kurdistan August 16, 2014. The YPG is training 55 Yazidi recruits with skills to help them fight against the Islamic State militant group. Proclaiming a 'caliphate' straddling parts of Iraq and Syria, the radical Islamists have swept across northern Iraq in recent weeks, pushing back Kurdish regional forces and driving tens of thousands of Christians and members of the Yazidi religious minority from their homes.
