Australian police have seized what they say is one of the largest hauls of illegal drugs ever made.

Crystal methamphetamine and heroine, worth more A$500m (US$526m; £335m) were hidden in an imported shipment of terracotta pots.

Four Hong Kong citizens and three Australians were arrested during raids in Sydney following a year-long investigation.

Details were given at a news conference by Border Protection Service Chief Operating Officer Michael Pezzullo and Deputy Police Commissioner Andrew Colvin.
