At least three school children are among 17 people killed in a suicide car bombing in north-west Pakistan.
The attacker rammed a pick-up into a police station in Lakki Marwat town, in Khyber Pakhtunkhwa province.
Books and a school-bag could be seen in the wreckage. The dead included 11 police officers.
More than 100 people died in attacks on Shia Muslims in Pakistan last week, as violence resumed after flooding. The Pakistani Taliban claimed the attacks.
More than 40 people were wounded in Monday's blast at Lakki Marwat.
The bomber reportedly struck a school van before ramming the rear wall of the police station; the building collapsed.
A neighbourhood shop and mosque were also damaged.
Rescue workers and police officials dug through the rubble to reach those trapped.
"Seventeen dead bodies and 45 injured have been brought to our hospital," Dr Ghulam Ali, of Lakki Marwat's main hospital, told news agency AFP by telephone.
The Pakistani Taliban claimed responsibility for the attack, in a telephone call to the AP news agency.
They said that police were targeted because they had been encouraging residents to set up militias - known locally as lashkars - to fight the militants.
The Taliban pledged to carry out more attacks unless the militias disbanded.
