yrian rebels have seized twenty UN peacekeepers in the Golan Heights on the border between Syria and Israel. The United Nations Security Council demands the convoy’s immediate release.

A young fighter saying he was from the "Martyrs of Yarmouk" said the peacekeepers would not be set free until Syrian government forces withdrew from the village of Jamlah, a mile east of the ceasefire link with the Israeli-occupied Golan, Reuters reports.

"If no withdrawal is made within 24 hours we will treat them as prisoners," he said, claiming the UN forces had collaborated with Syrian government troops to drive the fighters out of the village.

After a video appeared on YouTube showing several armed-rebel fighters standing in front of two white armored vehicles bearing the UN inscription with at least five peacekeepers inside, the UN confirmed the incident.

UN deputy spokesman Eduardo del Buey told reporters that "approximately 30 armed fighters stopped and detained about 20 peacekeepers within the area of limitation."

"The UN observers were on a regular supply mission and were stopped near Observation Post 58, which had sustained damage and was evacuated this past weekend following heavy combat in close proximity, at Al Jamlah," the United Nations said in a statement issued in New York.

The UN Security Council demanded the peacekeepers immediate release. Russia’s UN envoy Vitaly Churkin said the seizure of the UN observers showed “gross disrespect for the United Nations.”

“Right now there are negotiations between UN representatives and the captors and we hope that the [UN] personnel will be released immediately as the UNSC demands,” Churkin said.

Mentioning an attack on Monday which killed 48 Syrian servicemen and nine Iraqi law enforcers, Churkin said the Golan incident showed “some people are trying very hard in order to extend the geography of the Syrian conflict.”

Human Rights watch said it was investigating the same rebel brigade for its role in a videotaped execution of detained Syrian soldiers posted on the Internet on Tuesday.

The capture of the UN observers points to how the situation on the ground in Syria is getting out of control and all sides are unable to control armed groups on the ground, Karl Sharpo, a Middle East blogger, told RT. He further warned that that there is no way of knowing whose hands outside aid will end up.

“The lines on the ground are very fluid, distinctions don’t really apply and you can’t make sure the weapons end up in the intended sites. Again if you look at the fact at what this incident illustrates is the lack of control that any military authority on the ground for the opposition or an outside political authority, doesn’t exercise the control it says it does,” Sharpo said.

he incident follows a statement on Wednesday by the Arab League offering military support to the Syrian rebels. Previously the League had only offered to support the Syrian opposition via humanitarian and diplomatic assistance.

Arab League Secretary-General Nabil Elarby told a press conference the Syrian Opposition Coalition had been formally invited to send a representative to attend a league meeting to be held in Doha in April.

The UK Foreign Secretary William Hague also announced on Wednesday that Britain will increase non-lethal aid to anti-government forces in Syria. The $19.5 million dollar package will include armored vehicles, body armor, search and rescue, disease prevention and communication equipment.
