The violence happened near a bus terminal in the city of Multan, about 600 kilometers southwest of Islamabad.
Senior police officials told reporters they suspected a suicide bomber riding a motorbike carried out the attack. Other officials blamed it on a remote-controlled device.
Hospital officials said several people were seriously wounded and feared the death toll could rise.
No one immediately claimed responsibility.
Multan and surrounding districts in the country’s populous Punjab province are known for hosting thousands of Islamic seminaries or madrassas with several allegedly linked to pro-al-Qaida and other militant organizations.
Separately, Pakistan’s military said at least 15 terrorists were killed and several of their hideouts were destroyed in airstrikes near the Afghan border on Sunday.
The raids targeted militants in the Shawal Valley in the North Waziristan tribal district, which is considered a key stronghold of militants linked to the Pakistani Taliban and those supporting the insurgency in Afghanistan.
