On 10 May 2013, the Philippine Secretary of Foreign Affairs, Albert del Rosario announced his intentions to pull out their contingent of UN peacekeepers from the UNDOF zone. He suggested the risks in the area had gone "beyond tolerable limits". The announcement followed the kidnapping of four peacekeepers, shown on video to be kept as human shields by the Yarmouk Martyrs Brigade. The total Philippine contingent numbered 342, approximately one third of the UN contingent at the time. On 6 June 2013 the Austrian chancellor Werner Faymann and Austrian foreign minister Michael Spindelegger announced that Austria would withdraw its troops from the UNDOF mission. This decision was made after Syrian rebels had attacked and temporarily captured the border crossing at Quneitra. A Filipino peacekeeper was wounded in the fighting.
