Two oil tankers were attacked within minutes of each other while passing through the Strait of Hormuz on Monday, the latest incidents affecting vessels in the Persian Gulf. A crude oil tanker owned by Saudi Arabia’s national oil company was struck by unknown projectiles about 16 nautical miles off the coast of Oman, while a Liberian-flagged supertanker operated by South Korea’s Sinokor was hit by three unknown projectiles. No casualties or environmental impact were reported. Maritime risk firm Marisks described the threat to commercial shipping as high and increasingly unpredictable, noting that Iran targets vessels based on affiliations with the United States and its allies rather than at random. Ships with links to the U.S., even if not directly owned by U.S. companies, face higher risk, as do Saudi-linked vessels. The firm said the situation is a repetition of the same pattern, with Iran having shifted from attacking Gulf neighbors to lashing out at vessels instead. Oil prices rose more than 2 percent on Tuesday after U.S. and Iranian attacks exchanged for the first time in a month, pushing the global benchmark for crude back above $90 a barrel.
