Cyber attack

DUBAI - Iran will retaliate against any country that carries out cyber attacks on its nuclear sites, the head of civilian defence said, after a fire at its Natanz plant which some Iranian officials said may have been caused by cyber sabotage. The Natanz uraniumenrichment site, much of which is underground, is one of several Iranian facilities monitored by inspectors of the International Atomic Energy Agency (IAEA), the UN nuclear watchdog.
