DAMASCUS, Oct. 27 (Xinhua) -- At least six Syrian children were killed on Thursday by rebel mortar shelling on government-controlled areas in the northern city of Aleppo, state news agency SANA reported.
The shelling targeted the National School in the Shahba neighborhood in Aleppo, as well as residential areas in the Hamadaniyeh neighborhood in western Aleppo.
SANA said the rebels in the Zahra neighborhood targeted the school.
The attack came just a couple of days after the Syrian Observatory for Human Rights monitor group said Russian airstrikes on rebel-held areas in the northwestern province of Idlib killed 22 school children.
Russia's foreign ministry said on Thursday Moscow is not responsible for an airstrike on the school.
Russia's Foreign Ministry Spokeswoman Maria Zakharova said Russian military were not involved in the attack.
Violence has reached a new high in Syria recently after efforts to revive a cessation of hostilities failed in the war-torn country.
