At least 10 people have been killed in multiple explosions inside a cinema in the city of Peshawar in north-west Pakistan.
It is not immediately clear who carried out the grenade attack.
The BBC reports owners of film theatres in Peshawar earlier complained of receiving warnings to close their businesses.
Insurgents denounce cinemas as immoral and un-Islamic for screening 'pornographic' films.
Explosions at another cinema in the city killed five people two weeks ago.
