Every week for many weeks, you get more of this drumbeat.

So today, more countries, more governments urge their citizens to leave Iran as soon as possible.

China, India, Canada.

Another embassy temporarily withdrew its staff.

At this time, it was the United Kingdom.

More governments issue travel advisories.

Don't travel to Israel.

Don't travel to Lebanon.

Don't travel to Iran.

And then adding to that, President Trump's comments.

President Trump continues to say that he hasn't made up his mind yet and he is the commander-in-chief.

Our chief international correspondent, Lise Doucette.

As well as Iran, the US is also negotiating with Cuba, according to President Trump.

The Caribbean island is suffering an economic crisis made worse by US action against Venezuela, which had been a key supplier of oil to Cuba.

President Trump has now suggested what he called a friendly US takeover of Cuba and said the US Secretary of State Marco Rubio was holding high-level talks with Cuban officials.

Our correspondent Will Grant has recently returned from Cuba, so how will the US President's comments go down there?

The first thought really is that anything that says it's going to be a friendly takeover from Washington, I mean, basically anywhere in Latin America, but certainly in Cuba, is unlikely to go that way.

No nation wants a takeover by Washington.

It's riven into the DNA of its people to reject that.

Particularly true in Cuba, I should say.
