At least 11 children were killed in Damascus when terrorist mortar attack targeted a school in an eastern district of the Syrian capital, a monitoring group said on Wednesday.

The attack occurred in Qaboun, a district in the east of the city.

The opposition UK-based Syrian Observatory for Human Rights stated that the death toll was expected to rise because a number of those wounded were in critical condition.

Syria was hit by a violent unrest since mid-March 2011, where the Syrian government accuses foreign actors, mainly the Saudi Arabia and Turkey, of orchestrating the conflict by supporting the militant opposition groups with arms and money.
