JERUSALEM, Israel -- Syrian opposition forces abducted 21 U.N. peacekeepers patrolling near the Golan Heights Wednesday evening.
The U.N. Security Council responded by condemning the abduction.
"The members of the Security Council strongly condemned the detention of a group of more than 20 peacekeepers," Russian U.N. Ambassador Vitaly Churkin, serving as rotating president of the Security Council, told reporters.
Filipino President Benigno Aquino III said negotiations for their release were underway.
The spokesman for the Philippine military, Col. Arnulfo Marcelo Burgos, said Syrian opposition forces abducted the soldiers on a routine military convoy, The Times of Israel reported.
"They were in a military convoy doing their run," Burgos said. "They were suddenly held at one Syrian rebel outpost. They were allowed to go through the first outpost but were stopped at the second outpost."
The rebel forces released two video clips of the abduction. In the second video, a spokesman accuses the U.N., Assad's government and the E.U. of "collaborating with Israel," promising that the "Free Syrian army will remain here until we banish Bashar [Assad] and his oppression."
The video accuses U.N. forces of assisting government troops to redeploy in an area captured by rebel forces in a fierce battle that killed 11 rebel fighters and 19 government troops.
According to the report, a spokesman for one of the Islamist brigades said they would not release the U.N. troops until Assad withdraws his troops from the Syrian village Jamla, about a mile from the Israeli border.
