TEL AVIV (Reuters) - At least one person was killed and nine others were wounded by a Palestinian wielding a knife in the popular Jaffa port area of Tel Aviv on Tuesday, authorities said, while U.S. Vice President Joe Biden was in a meeting a few kilometers away.

The attack took place along a boardwalk near a beach popular with tourists. The Magen David Adom ambulance service said four of the wounded had severely injuries.

"A terrorist, an illegal resident who came from somewhere in the Palestinian territories, came here to Jaffa and embarked on a run ... along the boardwalk. On his way he indiscriminately stabbed people," Tel Aviv mayor Ron Huldai told Army Radio.

He said a police officer had eventually caught up with the attacker and shot him dead.

Biden arrived in Israel late on Tuesday for a two-day visit, and was meeting former Israeli president Shimon Peres in Jaffa around the time of the boardwalk attack.

Three Palestinian assailants were killed earlier on Tuesday after carrying out separate attacks against Israelis.
