Iran may still have another operational nuclear facility. The US  knew that Iran had a lot of nuclear sites, probably three plus the one. But they had three main sites, US President Donald Trump said in an interview with Fox News.

At the same time, Reuters, citing sources in the International Atomic Energy Agency (IAEA), reports that after the US strikes on Iranian nuclear facilities, about 400 kg of enriched uranium disappeared from the IAEA's sight.

The IAEA believes that the nuclear fuel could be buried under the rubble, or moved to a secret location, DW reports.

Also, according to IAEA estimates, such stocks of enriched uranium are enough for Iran to create at least nine nuclear warheads.
