A Palestinian wielding a double-bladed dagger stabbed three Israelis on a crowded downtown street in Jerusalem Friday before being captured and beaten by bystanders, police said.

Prime Minister Yitzhak Shamir said he was sorry the Arab was caught alive."It is very grave, this vile deed which has occurred on the main streets of Jerusalem again. To my regret, the perpetrator was captured alive and this pains me greatly," Shamir said on Israel radio. The stabbing victims were not seriously injured.
