More than 1.7 million Syrian refugees will face a food shortage due to a "funding crisis," the United Nations World Food Program said Monday.

The WFP had to suspend its program providing food vouchers, which refugees use in Jordan, Lebanon, Turkey, Iraq, and Egypt, the agency said.

The program needs $64 million "immediately," it said, adding that the repercussions of suspending the vouchers "will be disastrous."
