JERUSALEM: The UN agency for Palestinian refugees on Saturday urged donors to remember more than half a million Palestinians caught up in the Syrian conflict when they meet at a conference in Kuwait next week.

"While all civilians in Syria are bearing the brunt of the violence, the present situation of Palestinians in Syria is exceptional," UNRWA Commissioner General Filippo Grandi said in a statement.

"They are becoming two-time refugees," Grandi said.

"Sadly, some 525,000 Palestine refugees in Syria are now suffering."

According to UN figures, more than 60,000 people have perished in the conflict that erupted in March 2011 after troops brutally repressed a popular uprising against the regime of President Bashar al-Assad.

"As donors make their pledges in Kuwait, I call on them to remember the Palestine refugees," Grandi added

Kuwait hosts on Wednesday an international donors conference to raise humanitarian aid to civilians caught up in Syria's bloody conflict.
