Russian forces occupy Ukrainian nuclear plant, witnesses report.

Witnesses report that Russian military forces have been fortifying defensive positions around the Zaporizhzhia nuclear power plant in southern Ukraine, including digging trenches, laying mines, and setting up firing positions on the plant's buildings. The increased military presence raises concerns about the safety and security of the facility in the event of a counteroffensive in the region. The UN nuclear watchdog has warned of the danger of a major accident at the plant and plans to present a deal between Russia and Ukraine to the UN Security Council to protect the facility.
