Rebels clash with Syrian troops near Lebanon border
Activist groups say at least 90 people killed
Rebel fighters and security forces in Syria clashed near the border with Lebanon and fought over a military barracks in Aleppo on Sunday, while Turkish artillery fired into Syria for a fifth consecutive day in retaliation for cross-border shelling. On Sunday morning, Syrian forces shelled Tal Abyad, a Syrian border town where rebels recently seized control, according to antigovernment activists. Video images posted online purported to show women and children fleeing the area.
