The UN is about to embark on a complex operation to avert an environmental disaster in the Red Sea, off the coast of Yemen, by transferring oil from a dilapidated supertanker to a specially chartered vessel. This risky mission aims to save the FSO Safer, an old tanker containing over a million barrels of oil, which has been moored for years near the coast of Hodeida, a port city in western Yemen, and is threatening to cause a huge oil spill. Despite the dangers posed by extreme temperatures and the presence of sea mines in the region, the UN hopes to eliminate the risk in around three weeks to avoid a potentially devastating ecological catastrophe for the flora and fauna of the Red Sea and neighboring countries.
