The death toll from a Syrian helicopter strike on a town near the northern city of Aleppo has risen to 26, activists said Sunday, AP reported. The Britain-based Syrian Observatory for Human Rights said the aircraft targeted a compound of the opposing group known as the Tawhid Brigade in the town of al-Bab. The bombs missed their target and hit the Nafasin market instead, killing 26 people, most of them civilians and including four children. Three of those who died in the attack were opposing fighters, said Rami Abdurrahman, who heads the Observatory.
