Demand for the iodine tablets has soared in Kyiv pharmacies after Zelensky has said this week that Russian forces controlling Zaporizhzhia -- Europe's biggest nuclear plant -- were planning a "terror attack" by orchestrating a radiation leak. "I saw that there is a checklist on social networks about the action plan, what to do, where to go. But I didn't run to buy iodine", says Kyrylo Zalunin a 37-year-old resident of Kyiv. Meanwhile, Kyiv has urged Ukrainians not to panic or stockpile iodine tablets. In a separate statement, the ministry warned against the adverse effects of incorrectly administering iodine, adding that it could even be fatal. IMAGES AND SOUNDBITES
