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.

But that might not be possible.

So this is having a huge knock-on effect, because it's not the only way that oil supply is harming life in Cuba.

Rationing is taking place, of course, in terms of cars.

People can only fill...

About half a tank they can only pay in US dollars.

Health services are being affected, public transport, schools are being shuttered.

I mean, it is a very, very bleak picture on the island right now.

It's a pleasure, David.

Yeah, you can.
