BEIRUT - Hundreds of Syrian women and children have crossed into northern Lebanon, fleeing gunfire on the Syrian side of the border, witnesses said on Thursday. Mahmood Khazaal, former mayor of the Lebanese border town of al-Buqaya, said 1,500 people had come on foot. Many crossed a river dividing the two countries because Syrian authorities had stopped them leaving through official border crossings."They are leaving their houses and their men. The women have come with their children," Khazaal told Reuters. "We heard shooting since 6.15 (1515 GMT Wednesday) and that's when they started fleeing."It was not clear how many people were hurt in the clashes."We fled from the shooting in the Tel Kelakh region," said one woman, who declined to give her name, referring to the area around a Syrian border town. "There was shooting which forced us to leave our country and flee. Our men are still surrounded."
