An explosives-laden car rammed into a security checkpoint in Pakistan's volatile northwest Saturday, setting off a massive blast that killed at least 12 people and wounded dozens more, police said. The suicide attack occurred on the outskirts of Peshawar on the day Pakistani lawmakers voted for a new president, underscoring the challenges facing the leaders of the U.S.-allied country.
