An imminent terrorist attack was averted Saturday in Pakistan's northwest city of Peshawar, when police recovered 15,000 kg of explosive material from a warehouse, a media report said.

Police found the explosive material and two pick-ups vans during an operation on Peshawar's Ring Road, Dawn News reported.

Two suspects were arrested, but the owner of the warehouse managed to escape, police said.

The two pick-up vans were used to transport potassium chloride for making bombs, police said.

Police said the material could mainly be used in making hand grenades.
