UN's Grandi calls for Yemen talks, fears refugee exodus

Escalating violence in Yemen could lead to a refugee exodus and will not end a war that has taken a huge toll on civilians, U.N. refugee chief Filippo Grandi said on Wednesday, as a Saudi-led coalition launched the largest assault of the war.

"It’s actually suprising that an exodus has not happened yet," he told Reuters. "The message is go back to the negotiating table as soon as possible."
