A bomb explosion has killed more than 25 people in Pakistan's northwestern city of Peshawar, police and hospital officials said.

Sunday's blast took place in the busy Kissa Khwani market in Peshawar -- gateway to the troubled tribal regions which are infested with Taliban and Al-Qaeda linked fighters.

"The blast killed more than 25 people," senior local police official, Tariq Ismail Karak, told AFP news agency.

Another police official, Gul Nawaz, who also confirmed the blast, said it took place immediately after a car stopped in the market.

Jamil Shah, spokesman for the Lady Reading Hospital, said six children and two women as well as 70 wounded had been brought to the hospital from the blast site.
