Ertharin Cousin, the World Food Program's (WFP) executive director, has asked donor countries to contribute more to the victims of the Syria conflict. The head of the United Nations agency said funding prospects were “bleak.”

Cousin said that the global community should keep supporting the children and the families who had been suffering the political unrest for five years now. She met with refugees in Amman, the capital of Jordan.

"Those boys, with their big dreams, none of them will be fulfilled because they live for today, and the today requires that they work," Cousin told The Associated Press, "The challenge is that, eventually, this crisis will end, and when it does, what happens to those boys, who today are working to help feed their families? They don't have a tomorrow."

Islamic State group forces earlier released 22 Christian hostages who had been held captive since February. According to the U.K.-based Syrian Observatory for Human Rights, tribal leaders had mediated to initiate the release.

Fox News reported that released hostages had been taken to the Virgin Mary Church in the city of Hasakeh, Syria. Facebook photos show a priest greeting the people -- which consisted of mostly elderly men and women. Some of them are seen in tears.

The Nusra Front, an al Qaeda affiliate organization involved in the Syrian civil war along with ISIS, said Monday that it would withdraw itself from conflict zones close to the Turkey border. The Nusra Front has been one of the strongest rivals of the ISIS militants.

More than four million Syrian people have been displaced since the conflict had started in 2011. Around 630,000 took shelter in Jordan while others went to Egypt, Iraq, Turkey and Lebanon.

The WFP provides food vouchers to around 440,000 refugees in Jordan. WFP has said that around 211,000 people, considered the most vulnerable, who receive food aid recipients get $14 each every month.
