There has been another explosion at the Fukushima Daiichi nuclear power plant in Japan. Japanese authorities say a hydrogen explosion occurred at Fukushima reactor No 3. It's not known yet if radiation leaked since the inner reactor container is reportedly intact, but a wall has collaped due to the explosion and three workers have been injured while seven others are missing.
Residents near the nuclear plant have been told to remain inside their house. Plant workers are trying to cool down fuel rods by pumping sea water to the reactors. Meanwhile a state of emergency has been declared at another nuclear plant - Onegawa - where excessive radiation levels were recorded.
