Around 8 million people are in need of food and water and 3 million people have been displaced to 3,000 different camps in Iraq according to the latest UN estimates, Rudaw has reported.
“What we are asking for now is half a billion dollars,” said Farhan Haq, a UN spokesman in New York.
“The needs are critical, especially after the large number of refugees who fled Ramadi,” he added.
Haq warned that the UN offices in Iraq might be closed if required funding is not provided for the humanitarian crisis.
The number of refugees who urgently need food and water is expected to rise from 8 to 10 million by the end of 2015, according to UN officials.
“As it says in the program on June 24, there will be a summit on the Middle East and Iraq may be discussed there, too,” Dato bin Ibrahim, head of the International Security Committee said. “But I leave this to the Security Council to see how they will tackle this topic,” he added.
It is feared the humanitarian crisis will worsen after ISIS took control of a large dam in Iraq’s Anbar province.
“Unfortunately, this is not the first time that water is being used as a weapon,” said UN spokesperson Stephane Dujarric. “We saw in 2014 how water was used for a bad aim in Anbar and caused a flood in Abu Ghraib,” he added.
The UN launched an appeal on Thursday for half a billion dollars in international aid to tackle a worsening humanitarian crisis in Iraq triggered by the conflict with ISIS.
The UN says that it has only received 40 percent of the $500 million it has asked the world to provide to Iraq.
