The sinking of Liberia-flagged, Greek-owned coal carrier, MV Tutor, has increased the risk of navigating the crucial Bab el-Mandeb chokepoint in the Red Sea to a new level and is also diving a fresh rise in insurance costs, gCaptain reported citing Bloomberg. The price of covering vessels for transit increased to about 0.6% from between 0.3% and 0.4%. Yemen’s Houthi militants struck the vessel with a seaborne drone, claiming the life of one crew member and injuring others.
