Russian Foreign Minister Sergei Lavrov is planning to attend a OSCE conference in North Macedonia this week.
The Organization for Security and Cooperation in Europe (OSCE), which includes Russia as a member, was set up in the Cold War to facilitate peaceful international relations.
North Macedonia invited Lavrov to attend, however, the journey requires Lavrov to fly through Greek or Bulgarian airspace - both NATO members.

Ukraine and the Baltic Republics have already announced their boycott of the conference due to Lavrov's attendance:
