PESHAWAR - Paramilitary forces on Sunday raided a house in the northwestern tribal belt on the Afghan border and seized up to 500 kilograms of bomb-making material, an official said.
The raid was carried out in Shahkas village in Khyber district close to Peshawar, the capital of Khyber Pakhtunkhwa where forces are bogged down fighting militants.
At least 60 bags of potassium chlorate, mortar shells, timers, landmines, detonators, fuses, improvised explosive device circuits and gel explosives were recovered from the basement of the house, Colonel Mohammad Naeem Sarwar told AFP.
A suspect was arrested during the raid, which was carried out after a roadside bomb wounded three civilians in the area on Saturday, he said. "The site was being used to make bombs for terrorist activities in the cities of Peshawar, Islamabad and Lahore," Sarwar said.
Authorities last week said they had raided a car bomb factory in Quetta, confiscating more than 100 tonnes of chemicals which had been used in recent attacks.
Pakistan says more than 40,000 people have been killed in attacks by Al-Qaeda and Taliban-led militants in the last decade.
