Baluchistan province has been gripped by extremist activity, with Islamist militants linked to the Taliban, al Qaeda and Islamic State operating in the area, which borders Iran as well as Afghanistan. The indigenous ethnic Baluch insurgency is also actively fighting the central government in the province.

Siraj Raisani is the second politician to be killed during this year's Pakistani electoral campaign.
The recent rise in political violence in Pakistan comes amid a government crackdown on political gatherings and growing tensions over former Prime Minister Nawaz Sharif's return to the country and subsequent jailing, as he hoped to lead his party during the elections.
The Supreme Court ousted Sharif last year and convicted him in absentia a week ago on corruption charges.
Sharif's return to Pakistan to face prison defied expectation but Mushahidullah Khan, a spokesman for Sharif's Pakistan Muslim League, said Saturday that the former prime minister would appeal his conviction and apply for bail before Monday's deadline.
Sharif also faces two additional corruption trials, both of which will be held inside the jail, according to Khan. He said security was cited as the reason for the designated location.
