Three Pakistani soldiers have been killed and two others wounded in a roadside bomb blast in the northwestern tribal region of Kurram near the Afghan border, a government official says.
Javed Khan, a local administrator in Kurram Agency, said the bomb went off near an army vehicle in Dogar village on Monday.
No group has claimed responsibility for the attack. However, the pro-Taliban militants are often blamed for the deadly bombings.
The militants often attack security forces and civilians. They have killed thousands of Pakistani soldiers in recent years.
The militants have also managed to spread their influence in various regions of Pakistan, despite countermeasures taken by the Pakistani army.
