Thailand: About 80 pieces of plastic rubbish weighing eight kilograms were found in the stomach of a whale that died in Thailand after a five-day effort to save it, a marine official said on Sunday.

The pilot whale was discovered on Monday in a canal in the southern province of Songkhla and received treatment from a team of veterinarians.

The whale spat out five plastic bags on Friday and later died, the Marine and Coastal Resources Department said on its website.

"This plastic rubbish made the whale sick and unable to hunt for food," the department said.
