Iran has made a deal with the former Soviet republic of Kazakhstan to buy four nuclear warheads, the leading Iranian opposition group said Monday.
Mohammed Mohaddesin, director of international relations for the People's Mujahedeen, said Mujahedeen agents in Iran obtained information about the deal. The warheads have been paid for but not delivered, he said.
The Mujahedeen report comes a month after Kazakhstan's prime minister, Sergei Tereschenko, pledged on a visit to Israel that his country would sell none of the nuclear weapons it inherited with the breakup of the Soviet Union.
One U.S. official, who requested anonymity, said a claim similar to the Mujahedeen's had been made earlier this year, but U.S. officials had not confirmed it.
Another official cautioned that the Mujahedeen has a stake in any report that makes the fundamentalist Muslim leaders of Iran look bad.
However, the opposition group, which is based in Iraq, has provided accurate information on Iranian nuclear activities in the past.
