Ukrainian officials reported Saturday "abnormally high" radiation in areas of the Chernobyl Exclusion Zone, where they say Russian troops dug trenches and tried to build fortifications when they occupied the site until late last month.
Why it matters: It's one of the world's most toxic places due to the 1986 Chernobyl Nuclear Power Plant disaster. The International Atomic Energy Agency (IAEA) could not immediately verify claims of radioactive dust in areas of the zone known as the "Red Forest," but is due to send a team to the region to assess damage.
