About 50 whales have died after stranding themselves for a second time on a beach in Japan.
The animals were part of a pod of about 70 melon-headed whales that had been put back in the sea after beaching themselves in Ichinomiya on Tuesday.
Surfers and local residents had helped return the whales to sea, but by Wednesday morning some of the pod had run itself back up on the shore.
Scientists plan to do tests to find out why the whales ran aground.
