Trenches and firing positions sit in the highly radioactive soil adjacent to the Chernobyl nuclear power plant near Chernobyl, Ukraine, Saturday, April 16, 2022. Thousands of tanks and troops rumbled into the forested exclusion zone around the shuttered plant in the earliest hours of Russia’s invasion of Ukraine in February, churning up highly contaminated soil from the site of the 1986 accident that was the world's worst nuclear disaster.
