LONDON, July 6 (Reuters) – Britain said its aircraft carrier in the Norwegian Sea was repeatedly approached by a Russian patrol aircraft, before being escorted away by UK fighter jets, in the latest incident risking a potential escalation between NATO and Russia. The incident, which Britain called “unsafe and unprofessional”, comes ahead of a NATO meeting in Ankara on Tuesday, where NATO members are set to pledge €70 billion in military assistance to Ukraine for 2026.
