Humanitarian aid is being distributed to hundreds of thousands of Yazidi people, fleeing Islamic militants in Northern Iraq.
Unicef representative Marzio Babille told the BBC it was one of the largest humanitarian responses he had seen in 50 years.
He said: "We need more international partners stepping forward and multiplying camps, food distribution, water distribution to a level of dignity that the United Nations aspires to."
