Fears of a nuclear disaster in Japan were heightened today after a second explosion at the stricken Fukushima Dai-ichi number one plant.
A hydrogen explosion rocked Unit three of the plant sending a plume of smoke into the air - as engineers frantically tried to reduce pressure in the overheating reactor.
The blast follows a similar explosion at Unit one of the facility on Saturday and another reactor at the plant has also lost its cooling capacity, raising the risk of another explosion. Eleven people, seven plant workers and four army personnel were injured in today's explosion, one of them seriously.
