Jihadists in Aleppo Call For Mobilization Against Syrian Forces
The Islamic State of Iraq and the Levant
A jihadist rebel group affiliated to al-Qaeda has joined calls for a mass mobilisation in the Syrian city of Aleppo to halt a government advance.
A statement by the Islamic State of Iraq and the Levant (ISIS) urged "all brigades and Muslims to face off against the enemy", activists said.
On Monday, six other Islamist rebel groups issued a call to arms in Aleppo.
It came after the army secured the area around the city's airport and retook a strategically important base nearby.
