The US is carrying out an operation to seize a tanker linked to Venezuelan oil, an official tells CBS, the BBC’s US partner.

Previously named Bella 1, its name has been changed to Marinera and it has also reportedly been reflagged from a Guyanese to a Russian vessel.

Russia has reportedly deployed a submarine and other vessels to escort an oil tanker - which is also being pursued by US forces - across the Atlantic.

The ship, currently between Iceland and the British Isles, has been accused of breaking US sanctions and shipping Iranian oil. It has historically transported Venezuelan crude oil but has reported to be empty at the moment.
