SECOND World War saboteur Joachim Ronneberg, who headed a team which blew up a heavy water plant which Nazi Germany could have used to produce nuclear weapons, has died at the age of 99, Norway’s prime minister said.

Ronneberg was tapped by the British Special Operations Executive to destroy key parts of the heavily guarded plant in 1943.

The operation has been recounted in books, documentaries, films and TV series.
