Palestinian militants, including a leader of the Islamic Jihad group claimed to be behind Friday's Tel Aviv nightclub bombing, on Monday denounced the attack and said it was the work of outside forces.

As Israel announced a diplomatic offensive against Syria, which it alleges was behind the bombing that killed five Israelis, a wanted Fatah militia leader said: “It is clear that some resistance cells are infiltrated. We are not in a position to name Syria or Hizbollah but probably there is money coming from abroad.”
