Vanuatu Police have reportedly seized more than 600 kilogrammes of cocaine from a yacht in Port Vila harbour.
The seizure was made in a joint operation with the Australian Federal Police.
Police sources say it is the biggest cocaine haul in the history of Vanuatu and possibly also the region's biggest.
Police could not reveal where the cocaine came from but it's understood to have been destined for Australia.
The office of Vanuatu's Police Commissioner says information about the seizure will be released at a news conference today.
