SALZBURG, Austria — The U.N. nuclear agency says Iran is poised to double output of higher-enriched uranium that can be turned easily into the core of a nuclear warhead.

The International Atomic Energy Agency's (IAEA's) finding is contained in a report it circulated Friday among the agency's 35-nation board and obtained by The Associated Press.

The report says Iran is technically ready within days to ramp up its production of 20 percent enriched uranium at its Fordo facility, doubling its present output and cutting in half the time it would take to acquire enough of the substance to make a nuclear weapon.

The report confirms information given to the AP on Thursday by diplomats accredited to the IAEA.

Iran denies any interest in nuclear arms.
