Overseas Filipino Workers (OFW), fill out documents upon arrival Saturday, March 9, 2013 in Manila, Philippines, from civil war-torn Syria. On Wednesday, a convoy of 21 peacekeepers were seized near the Syrian village of Jamlah, just a mile from the Israeli-controlled Golan Heights in an area where the U.N. force had patrolled a cease-fire line between Israel and Syria without incident for nearly four decades, with UN and Philippine Foreign Affairs officials are negotiating for their safe release. The Syrian rebels want the Red Cross to escort them out of the area because of fighting with Syrian government forces, the Philippine military said. (AP Photo/Bullit Marquez)
