The Russian Center for coordination and monitoring the cessation of hostilities agreement said the terrorists of Ahrar al-Sham and Jabhat al-Nusra have targeted military sites in al-Ansari neighborhood in Aleppo city and shelled a number of neighborhoods.

The center spokesman based at the Russian airbase in Hmeimim said in a statement on Sunday that the terrorists of the two terrorist organizations continue to shell al-Sheikh Maksoud neighborhood and military sites in Handarat, adding that heavy clashes erupted in al-Sheikh Maksoud neighborhood in which terrorists used armored vehicles.

The spokesman warned that Jabhat al-Nusra is taking advantage of the cessation of hostilities agreement and the presence of so-called “moderate opposition” groups in areas where its groups are based by redeploying its troops and completing its reserves of arms and ammunition.

He pointed out that the terrorist groups targeted on Saturday night with mortar cannons the area of al-Castilo, which is a commercial hub, Hanadart Camp and residential neighborhoods to the north of Aleppo city.

The cessation of hostilities agreement came into effect on February 27 and it does not include ISIS, Jabhat al-Nusra and other groups designated as terrorist organizations by the UN Security Council.
