A powerful blast targeting a military vehicle on Saturday night killed at least 15 people and wounded 32 others in Pakistan's southwestern province of Balochistan, which borders Iran and Afghanistan, officials said.
The blast occurred at a bus stop in the provincial capital Quetta and the area caught fire soon after the explosion.
A statement by the Pakistani military said the explosion targeted an on-duty vehicle and set several other vehicles on fire.
"Incendiary explosive was used. As a result nearby vehicles caught fire. 15 people including 7 civilians were martyred," the statement said, adding that 25 people including 15 civilians had been injured and taken to a military hospital.
Daesh claimed responsibility for the attack.
Provincial home minister Sarfraz Bugti and government spokesman Anwar ul Haq Kakar confirmed the death toll but put the number of wounded at 32.
Bugti said firefighters were working to put out the blaze.
President Mamnoon Hussain, Chief of the Army Staff Qamar Javed Bajwa and deposed Prime Minister Nawaz Sharif all condemned the attack.
The blast came two days before Pakistan's 70th Independence Day, and the military chief said it was an effort to mar celebrations.
"Our resolve won't succumb to any challenge," he said in a statement.
Militants in past have carried out big attacks on Independence Day and other events of national importance.
