A Russian fighter jet has been filmed forcing a US F-15 to turn away and change course by flying dangerously close to the American aircraft, writes dailymail.co.uk.

In footage circulating on Russian social media, the Su-27 fighter comes into frame and makes a sharp left to bank across the F-15 from the side.

The US-made plane has no choice but to move out of the way as the Russian jet came within feet of hitting it. 

The 40-second clip was uploaded to Twitter on Thursday but it's not known where the altercation took place.

Commenters on social media claimed the manoeuvre was executed over the Baltic Sea as a part of a Baltic Air-policing mission.  

The Pentagon said that a Russian jet came dangerously close to one of its fighters over the Black Sea on Monday.

It said the Russian aircraft intercepted a US Navy patrol plane in international airspace, coming within five feet of the American plane, according to CBS.

Pentagon spokeswoman Captain Pamela Kunze said the Russian plane flew close to the plane for two hours and 40 minutes before crossing directly into its flight path.  

It's not known if it was the same incident shown in the footage, or just the latest in a series of close calls between Russian and U.S. aircraft over the Black Sea.
