PESHAWAR: An explosion at Peshawar's Mina Bazar on Wednesday, has left at least four people injured including a child, said police officials.

The bomb disposal squad AIG Shafqat Malik said that three hundred grams of explosives was used in a timer device.

The station house officer of Kotwali police station Ihsan Marwat said the bomb was planted to target a cold drinks shop.

He said the same shop had been targeted in 2013 and appears to be the result of a personal enmity, although they are probing the incident.

Mina Bazar has been the target of a number of bomb attacks, the most deadliest of which was on 28 October 2009, in which a car bomb left 137 people dead and over 200 others injured.
