BEIRUT (Reuters) - A suicide bomber driving a fuel tank blew himself up on Monday at a checkpoint run by Islamist group Ahrar al-Sham in Syria's northern city of Aleppo killing at least seven of its members, a monitoring group said.
The Syrian Observatory for Human Rights also said that four of the group's commanders are believed to be among those killed. Ahrar al-Sham officials were not immediately available for comment.
