Gunmen attacked Hamas officials in two separate incidents in the West Bank on Saturday, as weeks of factional violence in the Gaza Strip appeared to be spreading to the West Bank as well. In the first incident, gunmen stopped the car of Nablus' deputy mayor, Mahdi al-Khamdali, pulled him out and took him away in a separate car, security officials said. Al-Khamdali is a member of Hamas. There was no immediate claim of responsibility, but the officials said they believed the kidnappers were supporters of the rival Fatah group. In the West Bank town of Ramallah, meanwhile, gunmen stormed the offices of the Hamas-controlled Interior Ministry, shot the office manager in the legs and took him away, Palestinian security officials said. The man, also a Hamas supporter, was released in a nearby town and hospitalized, the officials said.
