Five people have been killed in two attacks in Israel and the occupied West Bank, officials say. In the first attack, two Israelis were stabbed to death by a Palestinian man at the entrance of a shop that serves as a synagogue in the city of Tel Aviv. Later, a third Israeli, a Jewish American and a Palestinian were killed in an attack near a Jewish settlement. A wave of violence over the past two months has claimed the lives of 15 Israelis and dozens of Palestinians. Many of the Palestinian fatalities were knife-wielding attackers of Israelis, shot by their victims or security forces. Others have been killed in clashes with troops in the West Bank or in cross-border violence in Gaza.
