Russian pilots harassed a U.S. B-fifty two bomber flying about the Black Sea and in global waters, crossing inside a hundred toes of the bomber’s path, a maneuver the U.S. army known as “unsafe and unprofessional.”

The confrontation on Friday was the 2nd between U.S. and Russian army forces in a week. On Tuesday, many American troops operating in northeast Syria were being hurt when a Russian army auto struck their have, in accordance to U.S. officials. Some U.S. officials claimed they feel the collision was deliberate.

The maneuver Friday by Russian pilots, who were being operating two Su-27 Flankers, a fighter plane, produced turbulence for the American bomber and constrained its movement, in accordance to a U.S. army statement.

“Actions like these improve the likely for midair collisions, are unnecessary, and inconsistent with great airmanship and global flight rules,” Gen. Jeffrey Harrigian, commander of U.S. Air Forces in Europe and Air Forces Africa, claimed in the statement.
