A century after his father and mother fled Russia to escape the Bolsheviks, renowned mathematician Alexey Sossinsky found history repeating itself when Russian President Vladimir Putin invaded Ukraine.
Brought up in France and the United States, Sossinsky moved to the land of his parents' birth in 1957 and carved out a distinguished academic career.
But at 85, he is now an exile once more. When Putin launched the war last year, he left with two suitcases in the middle of the night.
