Children were among the 90 people Syrian antigovernment activists claimed were killed in a day of shelling by forces loyal to President Bashar al-Assad on Friday. The Local Coordination Committees of Syria called the attack a "barbaric act" in a statement, saying that "the campaign ended when the armed militias slaughtered entire families in cold blood." The violence reportedly began Friday when government forces fired on a protest in the town of Houla. The situation escalated when resistance forces struck back, causing the Syrian military to shell the area. A spokesman for the United Nations monitoring mission in Syria told The Associated Press that observers were traveling Saturday to the site of the attack.
