The BBC's Shoaib Hasan says the Taliban are strongly suspected of carrying out the attack
At least 24 people have been killed and more than 100 injured in a car bombing in the north-western Pakistani town of Charsadda, police say.
The blast occurred as shoppers thronged the main market in Charsadda, which lies north-east of Peshawar.
The attack is the third in as many days in North West Frontier Province.
More than 300 people have been killed in a wave of attacks as Pakistani troops launched an assault against the Taliban in South Waziristan.
Police say around 40kg of explosives had been placed in a car which then exploded outside a busy market. There was no immediate claim of responsibility.
The BBC's Syed Shoaib Hasan in Islamabad says ordinary citizens are increasingly being targeted in bomb attacks. Analysts believe this is because the militants are cornered and under great pressure by the military in South Waziristan.
Eyewitnesses said the explosion was so powerful that surrounding buildings were severely damaged.
