Police say a suicide bomber detonated his explosives outside a Shiite mosque in northwestern Pakistan as worshipers were leaving Friday prayers, killing 22 people and wounding more than 30. It's the latest apparent sectarian attack in the country.
Today's attack on the mosque happened in the town of Hangu in a province which has experienced previous clashes between the Sunni and Shiite communities that live there.
Shiite Muslims across Pakistan have increasingly been targeted by radical Sunnis who consider them heretics, and 2012 was the bloodiest year for the minority sect in the country's history.
Police say the bomber staged his attack at one of the mosque's exits leading to a bazaar.
