img_4200A fuel truck exploded in the busy center of a rebel-held town near Syria’s border with Turkey on Saturday, killing dozens of people and wounding dozens more, several sources said.

The Syrian Observatory for Human Rights said at least 48 people, mostly civilians, were killed when the tanker blew up in front of a courthouse in the northern Syrian town of Azaz.

Around 14 of the dead were rebel fighters or courthouse guards, it said.

Dozens more had severe injuries, said the Observatory, which monitors the violence in the country.
