In Ukraine, Russian and Ukrainian forces continue to trade heavy fire around the Russian-occupied Zaporizhzhia nuclear power plant, raising fears of a major radiation disaster. Over the weekend, Ukraine accused Russia of using positions near the plant’s six nuclear reactors to stage artillery attacks on nearby Ukrainian towns. Meanwhile, Russia’s Defense Ministry says it shot down a Ukrainian drone near the Zaporizhzhia plant’s nuclear waste enclosure. Russia also accused Ukraine of shelling the site several times, which Ukrainian officials deny. Officials have started handing out iodine tablets to some 400,000 people living near the plant to help protect them from a potential radioactive release. This comes as the U.N.'s International Atomic Energy Agency says a team of experts is on its way to Zaporizhzhia and will arrive later this week to evaluate the safety and security of Europe's largest nuclear power station.
