Our forces are there, pilots of the free world.

Everyone is coming to your aid.

Help has arrived.

Reaction from inside Iran itself has been limited as there are restrictions on communications in place.

But earlier, the BBC spoke to Fawood Izadi, who's at Tehran's university.

And Hamid Reza Golamzadeh, who works for a think tank on Iranian foreign policy in northern Tehran, told us what he has heard.

What is Iran's opposition saying?

Reza Pahlavi is the son of Iran's last shah and is a leading critic of the Iranian regime.

He's currently in exile in the US and addressed the Iranian people directly.

Now that the Islamic Republic is collapsing, my message to the country's military, police and security forces is clear.

You've sworn an oath to protect Iran and the Iranian people, not the Islamic Republic and its leaders.

Your duty is to defend the people, not a regime that's taken our homeland hostage through repression and crime.

Join the people and help bring about a stable and secure transition.

Otherwise, you will go down with Khamenei's sinking ship and his regime.

To find out more about the reaction inside Iran, I spoke to Gia Gol from BBC Persian.

This is a joint operation between the US and Israel.

The US will have access, presumably, to the intelligence of Mossad, the Israeli intelligence agency.

The US has indicated this is about regime change.

What are the chances that the Ayatollah will have been hit by any of these strikes?

And the Mossad, of course, do have extraordinarily good contacts inside Iran, don't they?
