Japan's Emperor Akihito tells nation: 'Don't give up'

Speaking in a rare television address on Wednesday, Japan's Emperor Akihito expressed his condolences to the victims of the tsunami.

As fears grew over radiation leaks at a nuclear power plant damaged in the disaster, the 77-year-old urged his people not to give up.

"I am deeply concerned about the nuclear situation because it is unpredictable," said the royal.

"With the help of those involved I hope things will not get worse."

He went on to thank those involved in relief operations, including foreign governments.

Friday's earthquake-turned-tsunami has devastated Japan's north east coastline and the death toll is estimated to be over 10, 000.

"We don't know the number of victims, but I pray that every single person can be saved," Akihito said.
