A suicide car bomber attacked a Pakistani military convoy in a troubled tribal region bordering Afghanistan on Wednesday, killing at least five soldiers, security officials said.
The bomber rammed his explosives-laden vehicle into the convoy near a checkpost at Mir Ali, a town in North Waziristan region, two officials in the area said on condition of anonymity.
"Five soldiers were killed, it was a suicide attack," one of the officials told AFP. He added that others were injured but exact details were not immediately available.
Chief Pakistani military spokesman Major General Waheed Arshad said he had received reports that four soldiers were killed and six injured, two critically, in an attack in Mir Ali.
"It is not immediately clear what caused the blast near the military vehicle," he said.
