Ukrainian President Volodymyr Zelenskyy accused Russia of "nuclear terror" Thursday as fighting continues around the Zaporizhzhia nuclear power plant in southeast Ukraine. Speaking during an international defense conference held in Denmark, Zelenskyy warned that Russia could cause "the largest radiation accident in history" at the Zaporizhzhia nuclear power plant, which is the largest nuclear plant on the European continent and among the largest in the world. "In terms of actual consequences, it could be even more catastrophic than Chernobyl," he said.

Zelenskyy’s comments follow days of international concern after the plant came under attack over the weekend as shelling fell around the site.
