Intelligence officials say a suicide car bombing has killed two paramilitary soldiers in Pakistan's tribal region near the Afghan border.
The two officials say the bomber rammed his car into the main gate of a Frontier Corps base in the Shawa area of North Waziristan on Wednesday morning.
They spoke on condition of anonymity because they were not authorized to talk to journalists.
Abu Baseer, a purported spokesman for a militant group called Ansarul Mujahideen, claimed responsibility for the attack. He says it was carried out in revenge for the death of former Pakistani Taliban leader Hakimullah Mehsud in a U.S. drone strike on Nov. 1.
He says the number of casualties was much higher.
