By Dan Williams JERUSALEM (Reuters) - A Palestinian stabbed and critically wounded an Israeli soldier on Wednesday and was shot dead by troops, the army and a hospital official said, a day after a visit by U.S. Secretary of State John Kerry to explore how to end eight weeks of violence. The attack occurred in the Israeli-occupied West Bank at a road junction near a cluster of Palestinian villages and Jewish settlements. Israeli media reported later that a top military officer said senior ministers should consider easing certain measures for Palestinians to reduce tensions, such as arming security forces and giving them armored vehicles to quell the violence.
