LAHORE, Pakistan - Bombings in two Pakistan cities killed 46 people Monday, as militants struck back in the wake of an army offensive against a Taliban stronghold in the northwest near the Afghan border. Two synchronized bombs ripped through a market in the eastern Pakistani city of Lahore about 9 p.m., igniting a massive fire that killed 36 people, authorities said. Hours earlier a suicide bomber killed 10 people outside a courthouse in the northwestern city of Peshawar.
