A roadside bomb exploded near a vehicle carrying paramilitary forces in a troubled tribal region of northwestern Pakistan on Saturday, killing four soldiers, officials said.
At least one solder was also wounded in the attack near the town of Mir Ali in North Waziristan, where remnants of the Taliban and al-Qaida are believed to be hiding. Mohammed Khan, a local government official said the bodies and the wounded had been taken to a military hospital.
Pakistan's army confirmed the attack and the casualties, but provided no details.
The attack came days after a suspected missile strike from neighboring Afghanistan destroyed an alleged al-Qaida hideout in the region, killing 32 militants, including Arabs, Uzbeks and Chechens.
