The U.S. says an American citizen was killed in the West Bank.

The Israeli military said two Palestinian teenagers fatally stabbed Tuvya Weisman and wounded another at a supermarket Thursday. The Palestinians were then shot and wounded by an Israeli bystander.

State Department spokesman Mark Toner said Friday that Weisman also was a U.S. citizen.

Toner condemned the attack and said terrorism has no justification.

He said the attack underscores the need for Israelis and Palestinians to reject violence, reduce tensions and restore calm.

It was the latest in months of near-daily violence between Palestinians and Israeli civilians and security personnel. Since mid-September, 28 Israelis have been killed. Israeli fire has killed more than 160 Palestinians. Israel says 115 were attackers. The rest died in clashes with security forces.
