The incident took place at the Samand Levies check post, situated along the China-Pakistan Economic Corridor (CPEC) route, one of the most critical road links in Balochistan.
According to security sources, the assailants opened indiscriminate fire on the check post before fleeing the scene undetected.
The Levies personnel who embraced martyrdom were identified as Maqbool, Khuda Bakhsh, Ejaz Ahmed and Muhammad Ali. Their bodies were shifted to the district hospital in Khuzdar, while law enforcement agencies cordoned off the area and launched a search operation to trace the attackers.
No group has so far claimed responsibility for the assault, but the region has witnessed a surge in attacks on security forces and infrastructure linked to major development projects.
The motive behind the attack is being investigated, and security has been tightened in and around the area.
Officials condemned the brutal killing of the Levies personnel and offered condolences to the bereaved families. They reiterated their resolve to bring those behind the attack to justice and maintain security along the strategic CPEC corridor.
