'Pakistan building fourth plutonium reactor'

An independent expert says Pakistan has begun building what appears to be a fourth plutonium reactor, increasing concerns that the volatile nation is creating more nuclear material than it can safeguard. David Albright of the Institute for Science and International Security said Thursday that commercial satellite images show construction has begun of a building near three other plutonium reactors at Khushab, outside Islamabad.
He said based on its footprint it probably is a fourth reactor. He said Pakistan may already have 100 nuclear warheads and currently is building about 10 more each year.
