A suicide bombing in northwest Pakistan near the border with Afghanistan killed three soldiers and three children, officials announced on Sunday.
The officials pointed out that the gunmen shot dead two minority Sikhs in Peshawar.
A military statement said the suicide bomber triggered his explosives-laden vest near a security forces vehicle in a village near the town of Mir Ali in the tribal district of North Waziristan.
The attack killed two soldiers in the vehicle on the spot and wounded another. In addition, three children who were playing alongside the road were critically wounded. All of the wounded were rushed to a hospital in a helicopter but none survived, according to the statement.
There was no immediate claim of responsibility for the attack but the military affirmed that the security forces and intelligence officials were combing the area searching for the bomber's handlers.
Media outlet indicated that the region was believed to be a safe haven for local and foreign militants for years.
