Cannabis herb with an estimated street value of €3.2 million has been seized by gardaí in Co Louth.

The discovery was made after gardaí from the National Drugs and Organised Crime Bureau intercepted a commercial haulage vehicle in Ballymascanlon, near Dundalk.

The cannabis was found concealed within a consignment of fresh vegetables.

Two men, aged 57 and 42, from Britain and Northern Ireland have been arrested.

They are being held at Dundalk Garda Station on suspicion of drug trafficking.

Gardaí say the operation is part of an ongoing joint investigation involving the National Drugs and Organised Crime Bureau and the UK's National Crime Agency.

The operation is targeting cross-border organised criminal activity.

Assistant Commissioner John O'Driscoll said the seizure was "very significant".
