"At the same time, the officials said, some rebel groups have prevented civilians from leaving and even killed or kidnapped those who demanded that insurgents leave their neighborhoods...Mr. Colville said the agency had heard reports that two armed opposition groups had abducted and killed an unknown number of civilians who asked them to leave their neighborhoods. He added that residents trying to leave the Bustan al-Qasr neighborhood may have come under fire from armed opposition groups, something that could amount to the war crime of hostage-taking."
