[2] The Klos C was built in 1996, in Saint Petersburg, Russia by the shipbuilders Severnaya Verf.

[3] On March 5, 2014, the Israeli Navy boarded the vessel in the Red Sea during Operation Full Disclosure, suspecting that it was carrying weapons destined for militant groups in the Gaza Strip from the Islamic Republic of Iran.

[5] After docking in the port city of Eilat, the Israelis unloaded the Klos C's cargo and discovered an additional 181 mortars, and 400,000 rounds of ammunition meant to be used in assault rifles.

[6] Following the search of the ship and confiscation of weapons found on board, Israel released the vessel and its crew, and the Klos C returned to service.

[citation needed] A UN expert panel later concluded that, while the shipment came from Iran, it was headed for Sudan rather than the Gaza Strip.
