In Jerusalem, two Palestinians wielding a meat cleaver and a gun attacked worshipers at a Jewish synagogue, killing four people, before the attackers were shot dead. Six people were injured. It was the deadliest such incident to hit Jerusalem since 2008. Israeli Prime Minister Benjamin Netanyahu has vowed to wage a “harsh response,” while Secretary of State John Kerry condemned the attack as an “act of pure terror.” The killings came a day after a Palestinian bus driver was found hanged in his vehicle in what Israeli authorities say was a suicide. The man’s relatives say bruises on his body show he was murdered.
