A new monitoring mission from the U.N. nuclear watchdog arrived on Saturday at the Russian-held Zaporizhzhia nuclear power plant in Ukraine for the first time through Russian territory, a Russia-installed head of the plant said.

KYIV (Reuters) - Ukraine said on Sunday it condemned a "breach of territorial sovereignty" by employees of the U.N. nuclear watchdog who visited the Russia-held Zaporizhzhia nuclear power plant in Ukraine via Russian-occupied territory.

A new team from the International Atomic Energy Agency (IAEA) arrived at the Russian-occupied Zaporizhzhia nuclear power plant in Ukraine on March 1, marking the first time the agency's monitors reached the site through the occupied territory.
