The container arrived at Pireaus on May 10 from India, while its final destination was a Libyan company allegedly tied to ISIS jihadists.
The container's cargo had been declared as towels and tablecloths. A similar container carrying opioid painkillers and destined to the same company in Libya was confiscated by authorities in Dubai last February. The total value of the confiscated pills is estimated to be more than 13 million dollars.
According to reports, pain relievers such as Tramadol and Captagon, are broadly used by members of ISIS as energy boosters.
