The Belgian authorities seized 600 kilogrammes of cocaine at Antwerp port on Saturday night, the East Flanders public prosecutor's office said.
The drugs were discovered in Linkeroever, on the left bank of the Scheldt River. Two minors suspected of involvement in the attempted importation were subsequently arrested. They will both be presented to a juvenile court within the next few days.
The public prosecutor's office refused to offer any more details about the case, citing the young age of the suspects.
