Gaza Strip ? Rival Palestinian forces clashed in Gaza on Sunday, killing two militants by throwing them out of high-rise buildings. Gunmen fired shots at the house of Prime Minister Ismail Haniyeh of Hamas.

There were no immediate reports of casualties in the attack early today on Haniyeh’s house in the Shati refugee camp next to Gaza City. The attack, apparently by the rival Fatah faction, was the first time in a month of infighting that Haniyeh was targeted.

In an especially grisly incident, Hamas militants kidnapped an officer in a Fatah-linked security force, took him to the roof of a 15-story apartment building and threw him off. Mohammed Sweirki, 25, from the Presidential Guard of President Mahmoud Abbas of Fatah, was killed in the plunge.
