Bomb kills six near girl's school in Pakistan

A roadside bomb has killed six people, including three foreigners, near a girls' school in north-west Pakistan, police said.

At least 32 people were wounded in the blast, which struck near a convoy heading to an inauguration ceremony for the school.

Police chief Mumtaz Zarin Khan said the blast in Lower Dir's Shahi Koto area was remote controlled.

As part of its offensive against militants in the north-west's Swat Valley, the Pakistani army has carried out operations in Lower Dir. Local tribes have also set up militias to root out insurgents taking refuge in the area.

Security forces and girls' schools have both been frequently attacked by militants in the region.
