A suicide bomber killed six people Thursday at a checkpoint close to an aeronautical complex in Pakistan reportedly associated with the country's nuclear weapons program.
The attack took place near a sprawling aeronautical complex in Kamra around 50 kilometers (30 miles) from the capital Islamabad.
The site is often mentioned by foreign military experts and research groups as a likely place for storing parts of nuclear warheads or the planes that can carry them. The army, which does not give information on where its nuclear weapons are stored, has denied that the facility has any links to the weapons program.
The attacker was reportedly riding a bicycle and blew himself up at a checkpoint on a road leading to the complex, said police officer Fakhrialim Raja. Six people were killed, four of them civilians, he said.
