Militants targeted a vehicle used by the military-run construction company, the Frontier Works Organisation (FWO), with a remote-controlled bomb in the South Waziristan tribal region on the Afghan border, killing one soldier and wounding two, local intelligence officials said.
The FWO is building roads in the restive region.
Separately, mortar bombs fired from Afghanistan wounded one soldier at a military check post near the border in South Waziristan, intelligence officials said. There was no independent confirmation of the cross-border firing.
Pakistan and Afghanistan have traded allegations of cross-border fire in recent weeks.
