Rebel groups including a hardline Islamist unit have seized a government army command centre in northern Syria, forcing more than 100 soldiers to flee, according to a monitoring group said.
The Syrian Observatory for Human Rights said that the Jabhat al-Nusra, a group suspected of having links with al Qaeda, helped rebels take over the site - part of the 111th regiment base in the Sheikh Suleiman region of Aleppo province.
Some fighters on the rebel and army side were killed, while around 140 soldiers fled to another military site in the area, the Observatory added.
Britain promised five million pounds to help opposition groups in Syria today - but stressed it would not be providing military aid.
Britain will expand its support to Syrian rebels with an extra £5 million of non-lethal practical assistance, the Foreign Secretary has said
