A suicide bomber detonated his explosive-laden vehicle at a police station's main gate in northwest Pakistan early Tuesday, killing at least six officers and wounding 25 others, officials said. Part of the building collapsed upon impact, local police officer Kamal Khan said.
Some militants also opened fire and a shootout ensued for hours between them and security forces before three attackers were gunned down, he said. Several officers were transferred to hospital in critical condition.
