A Pakistani security force convoy was attacked by a suicide bomber ramming them with a VBIED earlier, killing himself and injuring five soldiers. From Khaleej Times:
Earlier, Pakistani forces killed four suspected militants in a firefight after a rocket attack on their positions overnight in South Waziristan, local security officials said. Clashes between security forces and militants have been reported daily from the lawless region since the breakdown in July of a peace deal the authorities signed with pro-Taliban groups in September last year. Pakistan’s army said it killed 10 militants and injured a dozen others in clashes on Thursday which erupted after militants tried to ambush a security forces convoy on the Jandola road.
