A bomb blast in the Pakistan city of Peshawar has killed 31 people and wounded 70 in an area crowded with shops and families, according to police and hospital authorities.

The blast came a week after an attack by a Taliban faction on an Anglican church that killed more than 80 people.

Mr Khan said the dead policemen were found in the Jabai area of Frontier Region Peshawar, part of Pakistan's troubled tribal region.
The 23 policemen went missing before dawn on Thursday when militants armed with rocket-propelled grenades and automatic weapons attacked two posts in Frontier Region Peshawar.
Two policemen were also killed in the attacks.
