At least three people were killed and 20 injured Tuesday in a series of violent attacks around Israel, prompting the mayor of Jerusalem to call for the government to “immediately implement drastic measures” to protect citizens. Two people were killed on a bus in Jerusalem when two men opened fire and stabbed passengers; one attacker was reportedly killed and the other captured. In another part of Jerusalem, a man rammed into a bus station with his car then got out and started stabbing people. One person died in that attack; the attacker was shot and captured at the scene, police say. And in the town of Raanaa, another passenger was stabbed at a bus station, hours before another six were injured in another stabbing attack elsewhere in the town.
