KARACHI, Pakistan — Police say gunmen have wounded a prominent Sunni cleric and killed his three guards and his driver in an apparently sectarian attack in southern Pakistan.

Police official Imran Shaukat says the vehicle with Auranzeb Farooqi came under attack on Tuesday as the cleric was passing through the heart of the port city of Karachi. Farooqi leads Ahle Sunnat-Wal-Jamaat, a small political party.

No one has responsibility for the attack but Shaukat says it is linked to Monday's attacks in Karachi in which gunmen shot and killed three Shiites and a Sunni cleric.

Pakistan is a majority Sunni Muslim country, and most Sunnis and Shiites live peacefully together. But the country has a long history of sectarian attacks by extremists on both sides of the divide.
