Chornobyl and independence in 1991, sentence 1

On 26 April 1986 reactor 4 at the Chornobyl nuclear plant exploded; the authorities kept quiet for days, the May Day parade in Kyiv went ahead, and Sweden noticed the radiation first, like a neighbour smelling smoke before the family next door admits the kitchen is on fire.

Who acts: reactor, authorities, Day parade, Sweden, neighbour, family · What happens: explode, keep, go, notice, smelling, admit · To what, where: radiation, smoke, fire · Speech: someone speaks here
