JERUSALEM — The Israeli military set up roadblocks, cordoned off Palestinian villages and deployed reinforcements to the West Bank on Wednesday, a day after an Israeli settler was killed in a drive-by shooting by suspected Palestinian gunmen. Israeli troops have combed villages around the city of Nablus searching for the suspects in Tuesday’s attack near the Havat Gilad settlement, a military statement said. In the attack, 35-year-old Raziel Shevah was shot multiple times from a passing vehicle and was hospitalized in critical condition.
