The agreement, announced by the Syrian government last week, called for a three-day cease-fire to allow women, children and older men to leave a rebel-held part of the city while food was distributed to those who remained inside.
But the cease-fire was shaky from the start. Some residents refused to leave, fearing their departure would prompt the killing of the remaining rebels. Pro-government Facebook pages also criticized the deal and began a campaign called “No to feeding the gunmen.”
