Hello and welcome to News Hour from the BBC World Service coming to you live from London.
I'm Sean Lay.
In the course of the next hour,
we're going to bring you an update on that developing story going on right now in the North Atlantic in which the Americans have boarded a tanker linked to Venezuelan oil and seized it,
they say, in pursuit of a court order.
The ship had been reflagged in recent weeks to become a Russian registered ship and the Russians have sent a submarine to the area.
So we will bring you the latest on what we know in the course of the next few minutes.

I would like to see the shutdown of being in prison forever.
I would like to see more press freedom.
I would like to see that I'm not frightened of talking to BBC World Service.
These are my wishes and my desires.
