Iran's ambassador to New Zealand has suggested regime change is not at all close in his country.

The US President's threatening to destroy Iran's energy infrastructure if a ceasefire deal isn't reached.

Donald Trump also claims regime change has been achieved - because attacks have killed many of Iran's top leaders.

Thousands more US troops are descending on the region, with reports ground operations are possible.

Reza Nazar Ahari says the hierarchy in Iran remains.

"The same system we have already - of course, some of them have been assassinated."
