At least 32 people have been killed and 150 injured in a bombing at a mosque in the Pakistani city of Peshawar.
Early reports said a bomber sitting in the front row had blown himself up, but this has not been confirmed. No group has said it carried out the attack.
Peshawar police chief Muhammad Ijaz Khan told local media that between 300 and 400 police officials were present in the area at the time of the blast.
Prime Minister Shehbaz Sharif has strongly condemned it. In a statement, he said those behind the incident "have nothing to do with Islam".
He added: "The entire nation is standing united against the menace of terrorism."
The blast took place around 13:30 (08:30 GMT) during afternoon prayers in the north-western city, near the country's border with Afghanistan.
A rescue operation is continuing inside the mosque and "more bodies are being taken out," Peshawar city Deputy Commissioner Shafiullah Khan said to BBC.
