A tiny Islamist group on Thursday claimed responsibility for an attack on the security headquarters of Gaza's Islamist Hamas rulers.Jund Ansar al-Jihad wal Sunna -- The Soldiers of the Partisans of Jihad and the Tradition of the Prophet -- said in a statement that explosives they set off at the security compound on Sunday claimed several victims. Witnesses at the time reported no casualties from what they said was a grenade attack.
"We urge our jihadist brothers to join forces to conduct painful joint attacks against those miscreant apostates and end their reign," the statement said in reference to Hamas.
Hamas, which seized power in the Gaza Strip in June 2007, last month crushed another Islamist group called Jund Ansar Allah -- The Soldiers of the Partisans of God -- which challenged its rule. The subsequent clashes left the group's top two leaders and several Hamas policemen dead.
