Israeli forces shot and killed a Palestinian man during a raid in the West Bank city of Nablus on Monday, the Israeli army said.

Such killings have become less frequent in the Israeli-occupied West Bank since Palestinian President Mahmoud Abbas launched a security campaign with U.S. backing.

An Israeli army spokesman said troops entered Nablus to arrest what he described as a "wanted man".

When the man attempted to get away, the troops fired warning shots and then fired at his lower body, the spokesman said.

"He was hit and was transferred to an Israeli hospital, where he died of his wounds," he said.
