Europe may have to deal with a new flow of Sudanese migrants if a cease-fire agreement isn’t signed soon between Sudan’s warring sides and relief efforts aren’t strengthened, the head of the United Nations refugee agency said Monday.

“The Europeans are always so worried about people coming across the Mediterranean. Well, I have a warning for them that if they don’t support more refugees coming out of Sudan, even displaced people inside Sudan, we will see onward movements of people towards Libya, Tunisia and across the Mediterranean,” Filippo Grandi said. ”There is no doubt.”
