A car bomb exploded in the south Lebanese city of Sidon near Palestinian Ain Al Hilweh refugee camp killing a Fatah movement official. 
Security sources said the explosion targeted Fathi Zidan, a Fatah official, noting that security sources circled the scene of the operation. 
The incident came after a ceasefire agreement in the camp was reached two weeks ago in the wake of clashes in which three Palestinians were killed and tens inured. 
Ain Al Hilweh refugee camp is the most densely populated Palestinian refugee camp. It is one km squire and inhabited by 80,000 people.
