Islamic State has claimed responsibility for the suicide bomb attack in Pakistan's Balochistan province which killed at least 25 people, Reuters reported.
The group's Amaq news agency said a bomber wearing an explosive vest was responsible for the attack.
A bomb exploded next to a convoy of the deputy chairman of the Pakistan Senate in Baluchistan province this evening. The blast occurred in the town of Mastung, 50 km (30 miles) from the provincial capital of Quetta. Television footage showed a vehicle mangled by the blast.
At least 35 people have been wounded in the blast. Ten people are in critical condition in hospital, officials said.

Police confirmed senate deputy chairman Maulana Abdul Ghafoor Haideri was injured in the blast in Mastung district, east of the provincial capital Quetta.
Senator Abdul Ghafoor Haideri told Reuters minutes after the blast that he believed he was the target and he had sustained minor injuries.
"My convoy was going to Mastung and there was an explosion. There are many casualties as there were many people in the convoy," he told Reuters.
"It is not yet clear whether it was a planted bomb or a suicide attack," police official Safar Khan told AFP as he gave the toll.
Senator Abdul Ghafoor Haideri is the deputy chairman of the upper house of parliament. He is a member of Jamiat e Ulema Islam, a right-wing Sunni Islamist political party that is part of Prime Minister Nawaz Sharif's coalition government.
