The blast occurred late on Friday in the province’s Khash district, according to the local reports.
The explosion took place during clashes with the Taliban members that attacked local checkpoints last night. According to the local source, the fighting is still ongoing and the Taliban also suffered losses.
The Taliban and Afghanistan's president announced a three-day ceasefire timed to the Muslim holiday of Eid al-Fitr, which was underway from 24-26 May, but the violence renewed after it expired.
