Anti-nuclear activists have temporarily halted a train carrying waste that environmentalists describe as "the most radioactive in history" from France to Germany.<br /><br />The train, which has 123 tonnes of nuclear waste on board, was stopped in the French city of Caen as it headed for Gorleben in Germany on Friday. <br /><br />Greenpeace has criticised the transportation of the waste, saying that it had not been allowed to take radioactivity measurements to verify claims that it is not dangerous for the environment.<br /><br />Al Jazeera's Emma Hayward reports.
