Rescuers hope to move young male humpback from Baltic to North Sea after being stranded for a month near Lübeck

Rescuers trying to save a stranded humpback whale off Germany’s Baltic coast have coaxed the mammal on to a barge in the hope the vessel can take it to safety in deeper waters.

Amid intense media attention, the high-stakes rescue mission, funded by two multi-millionaires, is being watched by hundreds of onlookers, many of whom are camped nearby to monitor the spectacle.
