Pakistani officials say three security personnel have been killed in an ambush on a convoy carrying paramilitary troops in the restive southwestern province of Balochistan.
The attack on the Frontier Corps convoy took place on September 4 in Panjgur district, some 520 kilometers southwest of the provincial capital, Quetta.
Reports said a lieutenant colonel was among those killed.
Three other troops were reported wounded.
No group has yet claimed the attack, but a security official was quoted as saying it was presumably carried out by Baluch separatists.
The resource-rich Balochistan Province has been plagued by sectarian violence, Islamist militant attacks, and a separatist insurgency that has led to thousands of casualties since 2004.
