Greek authorities have seized more than €500m ($561m) in amphetamines smuggled in containers shipped from Syria.

According to Reuters, Greek law enforcement found 33 million pills of Captagon — a brand name of the drug fenethylline hydrochloride — weighing 5.25 tonnes in three containers. Authorities are reportedly investigating the possibility the pills were destined for China.

"It is the largest quantity that has ever been seized globally, depriving organized crime of proceeds that would have exceeded $660m (€586.45m),"
