(Reuters) - Islamic State on Saturday claimed responsibility for a suicide bomb attack a day earlier in northwestern Pakistan, the group’s Amaq news agency said.

It said the bomber had targeted Shi’ite Muslims in a market in Orakzai and put the death toll at 57. A government official on Friday said at least 25 people had been killed and 20 wounded.
