‘Everything is dead’: Ukraine rushes to stem ecocide after river poisoning

Russia is suspected of deliberately leaking chemical waste into a river, with deadly consequences for wildlife

Serhiy Kraskov picked up a twig and poked at a small fish floating in the Desna River. It's a roach. It died recently. You can tell because its eyes are clear and not blurry," he said. Hundreds of other fish had washed up nearby on the river's green willow-fringed banks. A large pike lay in the mud. Nearby, in a patch of yellow lilies, was a motionless carp. Everything is dead, starting from the tiniest minnow to the biggest catfish," Kraskov added mournfully.

Kraskov is the mayor of the village of Slabyn, in Ukraine's northern Chernihiv region. The rustic settlement - population 520 - escaped the worst of Russia's 2022 full-scale invasion. But the war arrived last week in a new and horrible form. Ukrainian officials say the Russians deliberately poisoned the Seym River, which flows into the Desna. The Desna connects with a reservoir in the Kyiv region and a water supply used by millions.
