Peshawar, Nov 16 (IANS) At least four people were killed and 25 injured Monday morning when a suicide bomber struck near a police station in the outskirts of this Pakistani city, an official said.

The blast took place at 7.45 a.m. in Badhbeer, which is located in the outskirts of the North-West Frontier Province capital.

District Coordination Officer (DCO) Peshawar Sahibzada Anis said four people died in the blast, Geo News reported.

The blast was so powerful that a nearby mosque collapsed, Anis said, adding some people may be trapped under the rubble.

The wounded include children and women.

A police official said that the blast was a suicide attack.

According to sources, the suicide bomber was taking his explosive-laden car to some sensitive place. On being asked to pull over, he blew himself up instead.

Pakistan has been struck by a series of terror attacks since Oct 5, when the latest wave of violence was unleashed by the Taliban which is battling the army in the rugged terrain of South Waziristan. Peshawar itself has seen seven attacks in this period, killing 224 people and injuring more than 400.

The city witnessed this year's worst terror attack Oct 28 when a massive explosion in a crowded market killed 117 people and injured over 200.

On Oct 9, 50 people were killed in a bomb explosion. Less than a week later Oct 15, one person died in a blast while the very next day 15 people were killed in a major explosion. While the Oct 23 blast left 15 people injured, five days later saw the horrific bombing in bustling Meena Bazar where 117 people died.

This month Nov 8, the Taliban struck again with a bombing that left 18 people dead and 39 wounded. On Nov 14, 10 people were killed and 20 injured in a suicide car bombing.
