Senior police official Babar Bakhat Qureshi said seven others were wounded in the attack in the city of Bahawalpore.
He says the motive behind the attack on the Sunni mosque was not immediately clear.
Pakistan has a history of sectarian violence often involving Sunni extremists targeting minority Shiite Muslims. But attacks on Sunni mosques are also common.
Bahawalpore is about 60 miles (100 kilometers) west of Multan, a main city in eastern Pakistan.
