An explosive and ammunition-laden vehicle with five suicide bombers apparently Afghan nationals tried to enter the FC Madadgar Centre, but security forces retaliated quickly and killed the attackers, the army said in a statement.
Four soldiers were injured in the firefight with the attackers, it added.
The attack was apparently in retaliation to the killing of a key commander of the Lashkar-e-Jhangvi in Kili Almas in the province last night, the army said.
No terrorist group immediately claimed responsibility for the attacks.
At least 12 people, including six security forces personnel, were injured in the blast.
