Three persons have been wounded in a bomb blast underneath Ghamra Bridge.
Clean workers were cleaning the area when they came across a strange object that exploded as they were examining it, Director of the civil defense department Sami Youssef told MENA on Saturday.
The makeshift bomb was placed by unidentified persons underneath the bridge, Youssef said.
Sappers are combing the area in search of more explosives, he noted.
