It's an impressive haul.

Four tonnes of ivory, with a market value of $6m. Customs officials in Thailand say it's the biggest seizure in the country's history.

The elephant tusks were tracked from the Democratic Republic of Congo for two months.

Officials say they were being transported to Laos, from where they believed the ivory would be sold to customers across Asia.
