Fears for whale stranded in London's Thames

Crowds gather on the river bank in London to witness the rescue of a whale stuck in the Thames.

Fears were growing in London on Monday for the fate of an infant whale that was rescued from the banks of the River Thames, only to swim upstream instead of out to sea.

While it was initially seen at around 10:00 am heading east towards where the Thames opens into the North Sea, the whale was later spotted returning upstream.
