A fire on an oil tanker and a cargo ship has killed one person and injured two others Saturday in South Korea, according to Yonhap News. The 2,692-ton tanker and the 24-ton cargo ship, docked side by side, caught fire at 1.04 am local time (1604GMT Friday) in the southern coastal city of Yeosu, according to that city’s coast guard.

The Liberty Ship was more than a freighter - it was a revolution in shipbuilding. Forged in 18 American shipyards, they were welded instead of riveted, assembled in modules like giant puzzles, and built faster than German submarines could sink them.

With all the different accidents out at sea where cargo ships lose dozens of shipping containers, it makes one wonder exactly how they're secured to the vessel.

Ukraine has hit a Russian cargo ship alleged to be carrying Iranian weapons in a drone attack on a Russian Caspian Sea port. The 5,200-dwt multipurpose Port Olya-4 (bult 2014) was struck in the operation against the terminal in Olya on Thursday, domestic media cited Ukraine's Special Operations Forces as saying.

The Russian dry cargo ship Port Olya 4 was seriously damaged, according to a report by Russian Telegram channel NEZYGAR. Sources assure that the seaport on the Caspian Sea suffered an attack by dozens of drones. At the same time, they hint that Azerbaijan may be involved in the incident.
