The soldiers were conducting a search operation in the Makeen area of the South Waziristan tribal district.
"Three soldiers were martyred and two others were wounded when a landmine planted by militants exploded," a senior security official told AFP.
A local intelligence official confirmed the incident and casualties.
Pakistan`s seven tribal districts bordering Afghanistan are rife with a homegrown insurgency, and are also strongholds of the Afghan Taliban and Al-Qaeda. (*)
