At least 12 people were killed and 18 others injured on Tuesday when a bomb blast hit near military installations in the eastern Pakistani city of Multan, a senior rescue official said.
"We have recovered 12 dead bodies and more than 18 injured. Most of the dead are civilians," said emergency services official doctor Kaleem Ullah, who was at the site of the blast.
"There were also some security men among the dead. This building belongs to the army. It's badly damaged."
Multan's police chief Saood Aziz told AFP that the explosives appeared to have been planted in a small pick-up truck, but it was not immediately clear if it was a suicide bombing, while the exact target was also unknown.
Multan is in Punjab province, which is still reeling from twin bomb blasts in its capital Lahore on Monday that killed at least 49 people and wounded 150 more at a busy market in the centre of the city.
