Pakistan nuclear projects raise US fears• Two reactors nearing completion at Khushab

Pakistan is continuing to expand its nuclear bomb-making facilities despite growing international concern that advancing Islamist extremists could overrun one or more of its atomic weapons plants or seize sufficient radioactive material to make a dirty bomb, US nuclear experts and former officials say.

David Albright, previously a senior weapons inspector for the UN's International Atomic Energy Agency in Iraq, said commercial satellite photos showed two plutonium-producing reactors were nearing completion at Khushab, about 160 miles south-west of the capital, Islamabad.
"In the current climate, with Pakistan's leadership under duress from daily acts of violence by insurgent Taliban forces and organised political opposition, the security of any nuclear material produced in these reactors is in question," Albright said in a report (pdf) issued by the independent Institute for Science and International Security in Washington.

Albright warned that the continuing development of Pakistan's atomic weapons programme could trigger a renewed nuclear arms race with India. But he suggested a more immediate threat to nuclear security arose from recent territorial advances in north-west Pakistan by indigenous Taliban and foreign jihadi forces opposed to the Pakistani government and its American and British allies.
