Hunkered in a basement, five-year-old Nikolai clasps a teddy bear as missiles explode in the distance.
The youngster, who is the son of a British expat, was due to go to kindergarten on Thursday. Instead, he was woken by the piercing sound of tracer fire, rockets and shells.
Since then, he has spent hours underground in the cold bunker of his flats complex in Kharkiv with a few toys for company.
