A Turkey-bound cargo ship loaded with heavy and light weapons was seized by Greek coast guard, a source said.
The ship was originally procured by a France-based Saudi arms dealer, and was loaded in UK and France.
According to the source, who spoke with the condition of anonymity, the shipment was supposed to be delivered to Lebanese MP Khalid al-Dhaher in the northern Lebanese port of Tripoli, and eventually to al-Nusra Front in Syria under the supervision of Turkish intelligence.
Abdullah al-Chahal, the spiritual leader of a notorious Salfi movement in Lebanon, has reportedly brokered the whole operation.
Al-Dhaher, a Lebanese MP for the northern city of Tripoli, has been overtly backing ultra-hardline militants fighting Syrian President Bashar Assad.
The shipment was finally released after Turkey allegedly paid $750,000 to an influential Greek official. The Greek authorities then declared that it has investigated the shipment and found out loads of cartridges used for fishing.
In September 2015, The Greek coastguard seized the Bolivian-flagged vessel Haddad 1 off the island of Crete. A search of its cargo revealed almost 500,000 rounds of ammunition and 5,000 rifles hidden a board.
Haddad 1 was heading to an Islamist-held port in Libya in a suspected “Oil for Guns’ deal.
