REPUBLIKA.CO.ID, JERUSALEM -- Two Palestinians armed with a meat cleaver and a gun killed four worshippers in a Jerusalem synagogue on Tuesday before being shot dead by police, the deadliest such incident in six years in the holy city amid a surge in religious conflict.
Three of the victims held dual US-Israeli citizenship and the fourth man was a British-Israeli national, police said.
Israeli Prime Minister Benjamin Netanyahu pledged to respond with a "heavy hand", and again accused Western-backed Palestinian President Mahmoud Abbas of inciting violence in Jerusalem.
Abbas condemned the attack, which comes after weeks of unrest fueled in part by a dispute over Jerusalem's holiest shrine.
A worshipper at the service in the Kehillat Bnei Torah synagogue in an ultra-Orthodox neighborhood of West Jerusalem said about 25 people were praying when shooting broke out.
"I looked up and saw someone shooting people at point-blank range. Then someone came in with what looked like a butcher's knife and he went wild," the witness, Yosef Posternak, told Israel Radio.
Photos distributed by Israeli authorities showed a man in a prayer shawl lying dead, a bloodied butcher's cleaver on the floor and prayer books covered in blood.
"We are viewing this as a terrorist attack," said police spokesman Micky Rosenfeld, who confirmed the four dead and that the two assailants, both from predominantly Arab East Jerusalem, had been shot dead by police.
