TEHRAN, Young Journalists Club (YJC) - Police official Wali Mohammad said the attackers tried to push their way into the Frontier Corps' post. One detonated his explosives when the officers asked them to stop. He says the second attacker was killed by a sharpshooter, AP reported.
A statement posted on a Daesh-affiliated website says two of its "martyrdom seekers" were behind the attack.
Mastung lies about 50 kilometers, or 30 miles, south of Quetta, the capital of Baluchistan province, AP reported.
Baluchistan has also been the scene of a low-level insurgency by separatist groups that demand a greater share of the province's resources.
