FILE - In this Feb. 9, 2010 file photo, UNRWA Commissioner-General Filippo Grandi speaks during a press conference in Amman, Jordan. Syria's fighting has uprooted more than half of the country's 530,000 Palestinians — descendants of refugees from a Mideast conflict half a century ago — and their situation is becoming increasingly desperate, the head of a U.N. aid agency said Thursday, May 23, 2013. The Palestinians in Syria are particularly vulnerable because of their refugee status, Filippo Grandi, head of the U.N. Relief and Works Agency, told The Associated Press in an interview.
