UNITED NATIONS (AP) _ Former U.N. weapons inspector Scott Ritter says he has been under investigation by the FBI for more than three years for allegedly spying for Israel.

The FBI spokesman James Margolin said Friday that the bureau would not comment on Ritter's claims.

Ritter discussed the spying allegations at Wednesday's screening of his new documentary on the U.N. Special Commission, known as UNSCOM. The commission was created after the 1991 Gulf War to ensure the destruction of Iraq's weapons of mass destruction.

``I was withdrawn from Iraq in January 1998 at the behest of the Federal Bureau of Investigation which was calling me an Israeli spy,'' Ritter said. ``It is an investigation that is ongoing to this day.''

Ritter, who resigned from UNSCOM in August 1998 after seven years as a weapons inspector, said he did cooperate with Israel as part of his job, and with the knowledge of his bosses.
