An American tourist has been killed and several people wounded in a spate of attacks targeting Israelis near Tel Aviv and in Jerusalem.
The American, named as Taylor Force, was one of 10 people stabbed by an attacker in Jaffa, south of Tel Aviv, according to a BBC News report.
US Vice-President Joe Biden was at an event close by at the time.
Earlier, two Israeli police officers were shot and wounded in Jerusalem. An ultra-Orthodox Jew was stabbed in Petah Tikva, near Tel Aviv.
