Canberra, Sep 25 (TIWN) Several pilot whales currently stranded off the west coast of Australia's Tasmania will be euthanised as they cannot be saved, officials said on Thursday.

Some 380 whales have already died in the country's worst stranding on record, the BBC said in a report. Rescuers have refloated 70 of the mammals, adding that there was hope for another 20.
