WATCH: Pentagon releases video of Black Sea drone incident

Russia has denied US accusations that its pilots acted recklessly in the incident on Tuesday over the Black Sea.

In a rare move, the Pentagon on Thursday released a de-classified video showing Russia's intercept of a US military surveillance drone downed over the Black Sea two days ago.

It was the first direct US-Russian incident since the Ukraine war began, worsening already tense relations between Washington and Moscow.

In the video, a Russian Su-27 fighter jet comes very close to the US MQ-9 drone and dumps fuel near it, in what US officials say was an apparent effort to damage the American aircraft as it flew over the Black Sea.

It also shows the loss of the video feed after another close Russian maneuver, which the Pentagon says resulted from the Russian jet's collision with the drone. It ends with images of the drone's damaged propeller, which the Pentagon says resulted from the collision, making the aircraft inoperable.

The video, which is about 40 seconds long, has been edited by the US military for length but shows events in a sequential order, the Pentagon said.

Russia has denied US accusations that its pilots acted recklessly in the incident on Tuesday over the Black Sea and instead has blamed "sharp maneuvering" by the drone for the crash, claiming that the jets did not make contact.

Reminder of the risk of direct confrontation

The incident over international waters was a reminder of the risk of direct confrontation between the United States and Russia over Ukraine, which Moscow invaded more than a year ago and which Western allies have supported with intelligence and weapons.

The release of the video followed separate calls on Wednesday between the top US general, Mark Milley, and his Russian counterpart, Chief of the General Staff Valery Gerasimov, as well as between US Defense Secretary Lloyd Austin and his Russian counterpart, Sergei Shoigu.

In remarks to reporters on Wednesday, Milley said it was clear that the intercept and harassment of the drone by Russian jets was intentional, but it was unclear whether the Russian pilots meant to slam their aircraft into the drone -- a move that could also put the Russian aircraft at risk.
