Pakistani authorities say militants overran a remote security outpost in southwestern Baluchistan province, killing six members of the paramilitary forces.

The Pakistani Taliban — known as Tehreek-e-Taliban Pakistan — claimed responsibility for the attack in Ziarat district early on Wednesday morning, saying in an Urdu-language statement that it was revenge for the deaths earlier of their comrades at the hands of the paramilitary Baluchistan Levies Force.

Qadir Baksh Pirkani, Ziarat district deputy commissioner, said the assault began in the early morning hours and that an investigation into the killing is underway.

Several insurgent groups operate in Baluchistan, including the Pakistani Taliban, a secessionist Baluchistan group and members of an Islamic State affiliate, which is based across the border in Afghanistan.
