A deadly blast has reportedly killed at least 15 people at an election rally in north-west Pakistan.

Dozens of people are believed to have been injured in the explosion.

The blast is believed to have happened near the stage at a rally of Jamaat Ulema Islam - Fazl (JUI-F), a religious party, in the tribal Kurram region, according to the BBC.

Pakistan's Taliban claimed responsibility for the bombing, according to international media.

This is the latest in a string of attacks on parties and candidates since campaigning began last month for the general election on May 11.
