The US military reported that a Russian fighter plane on Tuesday dropped gasoline on an American drone over the Black Sea before colliding with it and bringing the drone to a stop.
The unmanned MQ-9 Reaper was stopped by two Russian Su-27 aircraft over international waters, one of which clipped its propeller, according to US European Command.
The Su-27s repeatedly flew in front of the MQ-9 and dumped fuel on it before the collision, according to the statement. This was reckless, bad for the environment, and unprofessional.
The statement corroborated an earlier story by AFP about a drone incident.
The incident was confirmed by NATO ambassadors in Brussels, who added that they did not anticipate it to quickly escalate into another altercation.
