Two Israeli soldiers were killed in an attack in the occupied West Bank on Friday morning that also left two suspected gunmen dead, the military said, violence that is likely to heighten political tensions and security concerns ahead of Israel's parliamentary election next week.

Israeli police did not identify the suspects or specify their roles in the attacks, which came during a spike in settler violence during the annual Palestinian olive harvest season.

The attack on Heidi Levine and Palestinians during the sensitive olive harvest again highlights the rampant settler violence that Prime Minister Benjamin Netanyahu has blamed on a small number of troublemakers.

In Saturday's attack in the village of Taybeh, settlers targeted Belgium's consul general, French and Polish diplomats and Catholic representatives, Belgian Foreign Minister Maxime Prevot said.

Israeli settlers attacked Palestinian villages across the occupied West Bank on Friday, setting fire to cars and trees and beating residents and a Washington Post photographer, in the latest violence to disrupt the territory's annual olive harvest this month.
