Given the rising tensions between Hamas and Fatah and the fact that the intended target wasn't killed (such an inompetence), it is reasonable to suspect that Fatah is behind it.
(Haaretz) The car of a Hamas official was blown up in Gaza on Friday night, Al-Akhbar reported. It was the second such incident in recent weeks.
"Police have opened an investigation after a makeshift bomb blew up the car of Sheikh Sami Hams in Nuseirat refugee camp," south of Gaza City, a security official told AFP on condition of anonymity.
Witnesses said that the car was totally destroyed. Hams was not in the car at the time and no casualties were reported.
It was the latest in a series of unclaimed attacks in Gaza against both Hamas and Fatah officials. On January 22, unidentified assailants blew up a car belonging to a Fatah leader. Two days earlier, the car of the chief financial officer in the Hamas military police was bombed outside his home.
The bombing spree comes as political tensions mount in the Gaza Strip over the seeming failure of the Fatah-dominated Palestinian Authority to ease the Israeli blockade and repair the damage caused by last summer's war.
