PESHAWAR: At least 23 people were killed and 29 injured when a suicide bomber blew himself during Friday prayers at a Pakistan mosque in a tribal area bordering Afghanistan, says media reports from Pakistan.

DawnNews quoting security source said it was confirmed that the explosion was a suicide blast.

There was no immediate claim of responsibility, but Pakistani Taliban in particular routinely attack soft targets such as courts, schools and mosques.

The army launched an operation in June 2014 in a bid to wipe out militant bases in the northwestern tribal areas and so bring an end to the bloody insurgency that has cost thousands of civilian lives since 2004. Security has since improved though scattered attacks still take place.
