Witnessed live military intercept

Approx 1035-1047 over Gloucestershire UK. 1 bomber type aircraft on hard climb, fighter jet directly on its tail, 4 other fighter jets pass at extreme close range from 4 different directions in a star like formation, no fire so likely warning sorte. The 4 jets left the intercept leaving the single jet almost looking like it was being escorted.

Happened over heavily populated area at high altitude so no sonic booms i wasn’t the only locals to notice the airspace incident. Weather at the time was very clear sky. For those not British the bomber aircraft was headed towards The north north east.

Are we about to go hot?
