Libya seizes tankers in anti-oil smuggling operation
The Libyan government said the crew of the two ships were arrested by the coastguard after the gun fight with the alleged oil smugglers.
"The Libyan coastguard boarded the two tankers, one flying the Ukrainian flag, the Ruta, and the other, the Stark, flying the Congolese flag," said General Ayoub Qassem told AFP.
"The coastguards had monitored them from afar and waited until Friday morning to act."
The operation took place on Thursday off Sidi Said near Zuwara, a town on the central coast.
Qassem said the oil traffickers were heavily armed and were supported by small boats engaging in a three hour firefight with the coastguards.
The two tankers were overpowered with the crew taken back to the capital Tripoli, which included Ukrainians, Turks, Georgians and another three sailors whose nationalities were not revealed.
The Ruta was carrying around 3,330 tonnes of oil in its tanks, while the Stark had 1,236 tonnes and was about to be loaded with fuel when the coastguard arrived.
The crews of the two vessels were taken to Tripoli where they are to face prosecution.
Libya has the largest oil reserves in Africa and produced around 1.6 million barrels per day before the 2011 revolution.
