You can go on and on.

There's no fuel with which to fill car tanks.

There's no fuel with which to run generators.

Everything is being rationed to the most extreme degree.

And people who have to turn to the black market to find fuel are having to pay extremely high rates.

We're talking US$100 for 10 litres of fuel to run your generator.

So it's becoming...

Very difficult, particularly for those who don't have access to foreign currency.

Today there is more calm and there is government, there are armed forces, there is a security cabinet and there is a lot of coordination. So you can rest assured that peace, security and normality in the country are being safeguarded. Both the Mexican and the US authorities are claiming a great victory. I asked a Mexico correspondent Will Grant whether he thought they were right to do so.

Two tankers' worth of humanitarian aid has now made it to Cuba, sent from the government of Mexican President Claudia Sheinbaum.

They included more than 800 tons of basic goods, powdered milk, rice and beans, items desperately needed in this worsening humanitarian crisis in Cuba.

However, what wasn't on those tankers is what Cuba most needs in this moment, which is crude oil.

It's pretty significant first and foremost because Canada is the primary source of tourists to Cuba.

So the immediate impact will be there and Air Canada is saying that it's suspending its flights, that it will be ferrying out those customers who are still there, around about 3,000 they believe are still in the country and getting them home.

But of course this is having an effect on other airlines who are looking at their services, wondering exactly how they're going to do things because it's quite simple to

They cannot refuel in Havana.

So short-haul flights to Mexico and Miami should still run, but it is going to get increasingly tough for those flights from Turkey, Russia, Madrid and so on.

I think ultimately the intention of the Trump administration is to squeeze the island in every which way possible over fuel.

and by doing so, really damage its tourism industry in the short term and medium term.

Those airlines are watching this very, very closely, working out if they can refuel elsewhere and then jump across.
