Two roadside blasts in Pakistan's northwestern Khyber Pakhtunkhwa province killed at least seven people, authorities said on Saturday.

"A private pickup truck carrying passengers was targeted with a remote-controlled IED (improvised explosive device)," said Yasir Afridi, a police officer in Bannu district in Khyber Pakhtunkhwa province, which borders Afghanistan.

"The injured were being transported to hospital in a car for emergency treatment when a second IED exploded," Afridi said.

Five people were killed in the first blast and two in the second, according to Afridi. Three people were also wounded, he said.

There was no immediate claim of responsibility for the blasts, though suspicion is likely to fall on the Pakistani Taliban, known as Tehrik-e-Taliban Pakistan, or TTP, which has been linked to similar attacks in the past.Why Pakistan is fighting the Taliban it once backedTo view this video please enable JavaScript, and consider upgrading to a web browser that supports HTML5 video
