A pair of bombings at the election offices of a political party and an independent candidate in southwest Pakistan killed at least 26 people and wounded more than two dozen others, officials said Wednesday, the day before parliamentary elections are to be held.

The first attack hit the election office of Asfandyar Khan in Pashin, a district in Baluchistan province, said Jan Achakzai, the spokesperson for the provincial government. Officials said at least 15 people were killed in the attack and the wounded are being transported to a nearby hospital. Police said some of them were listed in critical condition.
