The United States reportedly suspects Syria of hiding several nuclear sites in addition to a secret reactor destroyed by Israel.
Citing U.S. officials, the Washington Post reported Thursday that the Bush administration wants the International Atomic Energy Agency to expand the scope of a planned inspection of Syria.
The IAEA has asked Syria for permission to examine a site bombed by Israeli warplanes last September. The CIA has said that was a secret, North Korean-built plutonium reactor. According to the Post, the United States is now arguing that at least three other Syrian locations should be looked at, too.
The IAEA, which is being stonewalled by Damascus, has acknowledged receiving requests for broader inspections in Syria but gave no further details.
Experts believe that any further nuclear sites in Syria may be part of a production chain leading to the alleged reactor.
