Palestinian gunmen opened fire at an Israeli army patrol near the West Bank city of Ramallah overnight, according to an Israeli military spokeswoman. "During a routine patrol during the night, shots were fired by Palestinians at a military vehicle near Ramallah without causing injuries. The vehicle was lightly damaged," she told AFP. The shooters were not apprehended, the spokeswoman said. Israeli troops routinely patrol throughout the West Bank, often carrying out arrests of Palestinians. Shooting at such patrols has become rare in recent years.
