ISLAMABAD, Pakistan (CNN) -- Bombings by militants have destroyed a government-run girls' high school and several shops in the Swat Valley of northern Pakistan, police said Friday.
Militants detonated an improvised explosive device at the school around 2am, destroying 10 classrooms and two offices, Officer Bashir Khan of the Kabal police station said.
The blast also damaged nearby homes. No one was hurt, Khan said, and no one claimed responsibility.
The school was in the village of Tatano Bandai in Pakistan's Swat Valley, about 93 miles (150 kilometers) north of Peshawar in the North-West Frontier Province.
Around the same time as the school bombing, militants blew up several shops, including barber shops and cell phone stores, in the Charbagh area of the Swat Valley, police in the region told CNN.
There were no reports of injuries from those attacks, but the power was out in part of the area, said Shaukat Ali Khan, the coordination officer for the Swat district.
Militants have destroyed more than 30 schools in the Swat Valley in the past month, according to the NWFP's Ministry of Education.
The region is home to radical cleric Maulana Fazlullah, who has called girls' schools un-Islamic and warned families to remove their daughters from such schools.
Pakistan's Taliban have denied involvement in school bombings.
