Armed militants have destroyed two government schools in Mohmand tribal district in north-western Pakistan, officials say.
Three schools have been destroyed in the area since Tuesday.
Two primary schools for boys were blown up on Tuesday night in the Safi area of Mohmand, a local official told the BBC Urdu service.
He said both school buildings were destroyed. The Taliban has claimed responsibility.
An area spokesman for the militants, Sajjad Mohmand, told the BBC that "local Taliban" carried out the Tuesday attacks and another attack on Monday in which a school, also in the Safi area, was blown up.
The BBC's M Ilyas Khan in Islamabad say that the Taliban have been attacking government installations, including schools, offices and health facilities for about two years.
Officials say more than 80 schools have been destroyed during this time.
Attacks on schools have increased in recent days after a long pause.
They coincide with renewed operations by the security forces in the area in which some civilians are reported to have been killed.
