Militants attacked a regional police headquarters and an army post in a former Taliban stronghold in northwest Pakistan before dawn Friday, triggering firefights that killed two police officers and three insurgents, security officials said.
The attack in the town of Tank in Dera Ismail Khan came three days after a suicide bomber in the same region rammed his car into a police station’s main gate and five others opened fire, killing 23 officers in this year's worst attack on troops.
