British surveillance aircraft were operating over the Black Sea near Crimea at the same time two B-52 bombers approached the disputed territory before turning back.
A Royal Air Force RC-135 and Sentinel were observed operating over the Black Sea.

The Open Source Intelligence Twitter account Intel Air & Sea followed the event earlier, if you don’t follow them then I’d suggest you go do that now.
This isn’t new, B-52 bombers performed a similar ‘mock run’ last year.
This happened not long after a B-52 bomber was intercepted by a Russian Su-27 fighter in international airspace over the Black sea in what NATO described as an ‘unsafe’ manner.
On Friday an intercept occurred as a B-52 bomber was entering Danish airspace. NATO say that a Russian Su-27, flying from Kaliningrad, followed the B-52 into Danish airspace. This is a video from earlier that day showing a "unsafe, unprofessional" intercept over the Black Sea. pic.twitter.com/OEM2gjUmb4

This happened as the the bombers were deployed to “fly over all 30 NATO members in one day”.
