Philippine peacekeepers trapped by rebels in the Syrian Golan Heights are “under attack”, Philippine Defence Minister Voltaire Gazmin says.
He said the assault had started early on Saturday, but gave no details on any casualties.
In recent days the Syrian rebels have taken 44 Fijian peacekeepers hostage in the area and surrounded 75 Filipinos manning two separate UN posts.
The rebels have also seized a crossing point into the Israeli-occupied Golan.
They are believed to include members of the al-Nusra Front, al-Qaeda’s affiliate in Syria.
Mr Guzman told reporters on Saturday that the Philippine soldiers had been attacked at one post, identified as camp 68.
The others, based at camp 69 about 4km (2.5 miles) away, are said to be safe.
