Bomb Explodes at School for Orphans of Syrian Uprising

Rebels claim school was being used by Syrian intelligence

An activist group and a Syrian official say a roadside bomb went off near a school building in Damascus, but that is where the government's account and that of Syria's rebels diverges.

Syrian security officials tell CBS News' George Baghdadi that four people were injured in the explosion. Baghdadi says the school building itself appeared undamaged from the outside. The school, Syrian officials said, is designated for children who have lost their parents in the country's now 18-month-old crisis.
