KARACHI (Reuters) - A bomb attack in a Shi'ite Muslim area of Pakistan's commercial capital Karachi killed 25 people and wounded 50 on Sunday, the police said.
Police Inspector General Fayyaz Leghari said a suicide bomber may have been behind the attack, the latest signal that Sunni militant groups are stepping up pressure on the minority sect.
