Several European nations have called on Russia to immediately halt its attack on the nuclear power plant in Ukraine. Russian troops shelled it this afternoon - starting a fire.
There have been conflicting reports about whether the fire compromised equipment at the plan.
The UN's atomic watchdog urged Russian forces to stop attacking warning of "severe danger" if the reactors were hit. Professor Tatsu-jiro Suzuki is a nuclear power expert from Nagasaki University, and a former Vice Chairman of Japan's Atomic Energy Commission.
