Taliban militants wearing police uniforms have freed around 250 prisoners in a gun and grenade assault on a prison in northwestern Pakistan, undermining and embarrassing the government's efforts to tackle the threat from the militants.
The gunmen launched their attack with a series of heavy explosions before firing rocket propelled grenades and machine guns.
They then calling out the names of those they wanted to free on loudspeakers.
The prison, in the central town of Dera Ismail Khan, houses Taliban and militants from banned sectarian groups.
