The UN nuclear watchdog has voiced concern after Russian forces claimed to have surrounded Ukraine's biggest atomic plant, and called for its workers to be left alone to do their jobs.

Rafael Grossi, the director general of the International Atomic Energy Agency (IAEA), said the Russian government had informed the agency that its troops had taken control of the area around the Zaporizhzhia plant in south-eastern Ukraine, the second biggest in Europe, housing six of the country's 15 reactors.
