Israel's military says it's deployed hundreds of troops in the West Bank after Palestinian gunmen killed a Jewish settler couple driving their children the previous day there.

Defense Minister Moshe Yaalon visited the site of the shooting Friday, promising to catch the attackers and blaming Palestinian President Mahmoud Abbas for inciting such violence.

Gunmen opened fire late Thursday toward a vehicle travelling near the Palestinian village of Beit Furik.

Eitam and Naama Henkin, residents of a Jewish West Bank settlement, were killed. Their four young children, who were seated in the back seat and watched their parents die, were otherwise unharmed.

The attack comes on the heels of a series of Palestinian rock and firebomb attacks. Israel has vowed to quash the threat and has increasingly been arresting offenders.
