(Reuters) - Twin explosions killed at least 56 people in the Pakistani city of Quetta on Thursday evening, a police official said, hours after a bombing in Quetta's market killed 11.

The death toll in the latest blasts could rise, according to Deputy Inspector of Police Hamid Shakil.

The first explosion, in a snooker hall, appeared to be a suicide bombing, local residents said. About ten minutes later, a car bomb went off, they said, and five policemen and a cameraman were among the dead from that blast.
