Australia, New Zealand and eco activists are disappointed - Japan is at whale killing again despite the International Court of Justice ruling, The Independent reports.
The Japanese Fisheries Agency said in a report that 30 minke whales had been killed during the April-June whaling season as part of its "research hunts" in the north-west Pacific Ocean.
They also said that another group of whalers were still hunting in a more remote part of the ocean.
Australia and New Zealand both hoped that the ICJ's March decision would bring the cruel practice to an end.
