In northern Ukraine, Russian troops have left the decommissioned Chernobyl nuclear power plant, site of the world’s worst nuclear disaster in 1986. Ukrainian officials say Russia formally agreed to hand back responsibility for protecting the contaminated site to them, and claim Russian troops near the plant suffered acute radiation poisoning after they were ordered to dig trenches in highly radioactive soil in an area of the Chernobyl Exclusion Zone known as the Red Forest.
In Kyiv, Ukrainian President Volodymyr Zelensky fired two top security officials, accusing them of being “traitors” to Ukraine.
