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

"A private pickup truck carrying passengers was targeted with a remote-controlled IED ... the injured were being transported to hospital in a car for emergency treatment when a second IED exploded," said Yasir Afridi, a police officer in Bannu district, adding that three people were wounded.

Pakistani President Asif Ali Zardari strongly condemned the IED explosion in Bannu District and expressed deep grief and sorrow over the loss of innocent civilian lives, according to a statement.
