Insurgents in northwest Syria attacked an army position Saturday killing and wounding more than 30 troops, opposition activists said.
The attack came days after Russian and Syrian warplanes carried out several airstrikes on the last major rebel stronghold in the northwestern province of Idlib and parts of Aleppo killing several insurgents.
The Britain-based Syrian Observatory for Human Rights, an opposition war monitor, said the Ansar al-Tawhid group, which is allied with al-Qaida, carried out the attack with its members first detonating a massive bomb and then storming the position manned by government troops.
The Observatory said the attack killed 11 soldiers and wounded 20 others.
Other activist collectives, including Amjad News, also reported the attack saying it killed and wounded dozens of soldiers without giving a breakdown.
There was no immediate comment from the Syrian government or state media.
