"There are a million people displaced this year and the projection is another million will be displaced inside Syria between now and the end of the year if the violence continues to escalate," said Yacoub El Hillo, the UN humanitarian coordinator in Syria, on Saturday.
El Hillo added that urgent action was needed to resolve the escalating conflict in Syria or refugees will keep flowing out of the Middle East region.
“Unless something big is done to resolve this conflict through political means, the human train that has started moving out of Syria and the neighborhood will continue to be running for many months to come," El Hillo said.
He also called for greater international support to help Syrians survive winter in their own homeland, warning that a possible harsh winter could escalate the situation in the war-hit Arab country.
