KARACHI, Pakistan — Police say a bomb has exploded in southern Pakistan, killing at least four people and wounding 25.
Senior police officer Abdul Khaliq Sheikh says the attack took place today in the neighborhood of Clifton in Karachi, the capital of southern Sindh province.
He says the blast in an upscale residential area badly damaged several vehicles and a nearby multi-story building.
No one claimed responsibility, but the attack took place a day after a bomb targeting prominent police officer Shafiq Tanoli exploded in another area of Karachi, killing the officer and three others.
The slain officer, who had survived several attempts on his life, was targeted for his active campaigning against terrorists.
The blast also comes as Pakistan government pursues peace talks with the Taliban.
