The security personnel have earlier also come under attack while carrying out relief operations in the quake-hit areas, a stronghold of Balochistan nationalists.
On September 27, militants fired on a helicopter carrying relief goods to Mashkai. The helicopter of National Disaster Management Authority Chairman Maj Gen Muhammad Saeed Aleem was also targeted with rockets on September 26, while it was on its way to Mashkai for earthquake relief work.
The first earthquake had hit Balochistan on September 24, killing at least over 500 and injuring hundreds more. Another quake furthered the damage when it struck the area on September 28.
Security officials said the worst affected district Awaran is highly risky for carrying out relief operations.
