Palestinian residents of the besieged refugee camp of Yarmouk wait at the gate of the camp to receive aid supplies from the United Nations on the southern edge of the Syrian capital, Damascus. The deteriorating situation brought on by Syria's civil war prompted the U.N. Security Council to call an emergency meeting Monday, April 6, 2015, to discuss Yarmouk, calling for safe evacuation for the Palestinians, protection for the refugees, and humanitarian access to the camp.
