Russia has deployed navy assets to escort an oil tanker also being pursued by US forces across the Atlantic, CBS News, BBC's media partner in the US, reported. 

The ship, which currently isn't carrying anything, historically has transported Venezuelan crude oil and was thought to be between Scotland and Iceland on Tuesday.

President Donald Trump said last month that he was ordering a "blockade" of sanctioned oil tankers entering and leaving Venezuela, a move the government there described as "theft", according to BBC.
