Eleven people were killed Thursday in separate bombings on opposite sides of Pakistan, authorities told the media.

A bombing at a busy downtown market in the southwestern city of Quetta left six people dead and 20 others injured, Dawn television said, citing police and paramedics.

The explosive device was mounted on a bicycle and caused extensive damage to surrounding vehicles, according to several media outlets.

No group claimed responsibility for the blast in Quetta, capital of the impoverished, strife-torn province of Baluchistan, where Muslim militants and armed separatists are active.

Prime Minister Nawaz Sharif issued a statement condemning the strike in Quetta, which came hours after another bomb killed five people at a restaurant in the eastern metropolis of Lahore. EFE
