NATO chief Jens Stoltenberg and Ukraine's President Volodymyr Zelensky are the key figures at a European Union summit underway in Brussels this Thursday, highlighting the importance of protecting the EU's eastern flank from Russian aggression and bolstering support for Tunisia to combat illegal migration across the Mediterranean.
Zelensky is to address the gathering by video link and Stoltenberg will have an early lunch at the EU leaders' summit in the European capital, but the biggest seat will be set aside for an item that is not officially on the agenda: the fallout from the stunning weekend mutiny in Russia.
