Russia's Lavrov Calls Decision to Block Plane 'Unprecedented':

Russian Foreign Minister Sergei Lavrov on Monday described as "unprecedented" a move by three eastern European countries to block his plane from travelling to Serbia, adding that he had yet to receive an explanation for their decision.

He said that he would instead invite his Serbian counterpart to visit him in Moscow, adding: "The main thing is no one will be able to destroy our relations with Serbia".

Bulgaria, North Macedonia and Montenegro - closed their airspace to an official plane that would have carried Moscow's top diplomat to Belgrade on Monday.
