Gunmen abducted a Polish engineer Sunday in Pakistan's volatile northwest, Associated Press reported. Officials said armed men in a car ambushed a vehicle carrying the Polish engineer early Sunday near the northwestern city of Attock. The assailants killed the three Pakistanis in the vehicle - the driver, a guard and an assistant to the engineer - before seizing the Pole, police official Faisal Manzoor said. Polish Embassy spokesman Piotr Adamkiewicz confirmed the abduction and said the victim worked for Geofizyka, a company based in the Polish city of Krakow that helps survey Pakistani oil fields.
