U.S. Secretary of State John Kerry said on Monday the refugee crisis in Syria is a global issue that all nations need to work to resolve.
Speaking at a news conference with German Foreign Minister Frank-Walter Steinmeier, Kerry said

"I want to be clear that the United States considers the refugee crisis to be global. The impact first was felt, obviously, by Jordan and Lebanon and Turkey, and they've borne an unbelievable burden in the course of these four and a half, four-plus years of war."

On Monday a senior official from the Saudi-backed opposition High Negotiations Committee (HNC) said the cessation of hostilities faced "complete nullification" because Syrian government attacks were violating the agreement.
The cessation of hostilities agreement, the first of its kind since the Syrian civil war began in 2011, is a less formal arrangement than a ceasefire.
It is meant to allow peace talks to resume and aid to reach besieged communities.
Kerry said he was concerned by reports that the Syrian government was creating obstacles for the delivery of humanitarian aid and hoped it would stop its officials and troops from taking medicines or other supplies from the shipments.
