According to the officials, it was a Russian Su-27 fighter that was equipped with missiles. According to them, the rapprochement occurred with the American RC-135 aircraft and the distance between the planes was supposedly about 5 feet.

According to the other official, the behavior of the Russian aircraft was "provocative" and was flying "erratically".

35 interactions between U.S. and Russian jets and warships

According to the FOXNews, since June 2, over 35 so-called interactions between American and Russian military aircraft and warships have been recorded in the Baltic Sea region.

However, as one American official said, "this incident is most noteworthy, as the US military considered it " unsafe. "

Before the day of the incident, the Russian Defense Ministry said it would treat any US aircraft as a potential target flying west of the Euphrates River in Syria, following the shoot-down of a Syrian jet by the US Navy jet that was targeting US aligned aircrafts.

For decades, the Russian military has supported Bashar Assad, the President of Syria and deployed dozens of helicopter gunships and fighter jets to shore up the Syrian boarder in September 2015.

In February, Russian jets buzzed the US Navy missile destroyer in the Black Sea, while five hundred US Army soldiers arrived in a port near to Romania.
