West Bank - Israeli troops have killed a suspected Palestinian attacker and wounded another at a northern West Bank checkpoint.

The military said Monday that two Palestinians threw an explosive device at the troops, who then opened fire. No soldiers were wounded.

Palestinian medics say a 21-year-old Palestinian died from gunshot wounds and a second was hospitalized with moderate wounds.

Last week Israeli police shot and killed a Palestinian teenager who allegedly attempted to stab security personnel at a West Bank checkpoint near Jerusalem.

Israel has faced a three-year wave of Palestinian attacks in the West Bank that have greatly decreased in recent months.
