The Al Qassam brigades, the armed wing of the Islamic Resistance Movement of Hamas, said that one of its fighters was killed and three others were injured after being attacked by gunmen in the center of Gaza City.Hamas blamed Fateh for the attack and said that Fateh gunmen fired at Mohammad Dieb Abu Karsh, 23, and killed him. Three other members were injured, one seriously.

Eyewitnesses reported that Abu Karsh was driving his car near Al Saraya compound in Gaza city when gunmen opened fire at him.

The three injured members were identified as Hilmy Abid, Mohammad Abu Namous, and Kamal Banat.

Hamas sources said that Abu Karsh survived a previous attempt on his life on May 16 last year. He was injured in the attack while another Hamas member, identified as Mohammad Al Tatar, was killed.

The attack could bring an end to the fragile truce between Hamas and Fateh, and could jeopardize the Mecca meeting in Saudi Arabia between Hamas and Fateh factions, headed by President Mahmoud Abbas from Fateh, and Prime Minister Ismail Haniyya from Hamas.
