A group of 43 UN peacekeepers in the Israeli-occupied Golan Heights have been detained by militants fighting the Syrian army, and the world body is working to secure their release, the United Nations said on Thursday, Aug 28, accordigng to Reuters.

The detained peacekeepers are from the Philippines and Fiji, a UN official told Reuters on condition of anonymity.

"During a period of increased fighting beginning yesterday between armed elements and Syrian Arab Armed Forces within the area of separation in the Golan Heights, 43 peacekeepers from the United Nations Disengagement Observer Force (UNDOF) were detained early this morning by an armed group in the vicinity of Al Qunaytirah," the UN press office said in a statement.

It added that another 81 UNDOF peacekeepers were being restricted to their positions in the vicinity of Ar Ruwayhinah and Burayqah.

"The United Nations is making every effort to secure the release of the detained peacekeepers, and to restore the full freedom of movement of the force throughout its area of operation,"

Israel captured the Golan Heights from Syria in a 1967 war, and the countries technically remain at war. Syrian troops are not allowed in an area of separation under a 1973 ceasefire formalized in 1974.

UNDOF monitors the area of separation, a narrow strip of land running 45 miles (70 km) from Mount Hermon on the Lebanese border to the Yarmouk River frontier with Jordan. There are 1,223 UNDOF peacekeepers from six countries.

The force's personnel come from Fiji, India, Ireland, Nepal, Netherlands and the Philippines. The United Nations said this week that the Philippines has decided to pull out of UNDOF, and from a UN force in Liberia, which is struggling with an outbreak of the deadly Ebola virus.

Blue-helmeted UN troops have been seized by militants several times during the Syrian civil war, now in its fourth year. In all those cases they were released safely.
