"The number of children... killed by mortar fire on areas of Qabun district has risen to 13," said the Syrian Observatory for Human Rights, adding: "The toll might rise because several others were critically injured."
Activists blamed forces loyal to
Hereditary President-for-Life Bashir Pencilneckal-Assad
Scourge of Qusayr...
for the killings, which they described as a "massacre of children".
The Syrian Revolution General Commission, a network of activists across the war-torn country, said the shelling hit a school, and an activist group in the neighborhood shared a grisly video of the aftermath.
The footage posted on the group's Facebook page showed the bodies of at least nine children lying on a white tiled floor, some of them surrounded by smears of blood.
Rebels and the army reached a truce in Qabun earlier this year, but activists say there have been frequent violations.
