Filippo Grandi, head of the U.N. Relief and Works Agency (UNRWA), gestures during an interview in Beirut February 25, 2014. Filippo Grandi, head of the U.N. Relief and Works Agency (UNRWA), which cares for Palestinian refugees, visited Yarmouk on Sunday, where partial humanitarian access was granted this year but up to 20,000 are besieged. Grandi told journalists in Beirut on Tuesday that the resolution is "stronger than any other tool we've ever had before in Syria" and that the government had given him verbal promises that aid access to the camp would continue.
