Iran has ramped up its maritime operations by seizing several oil tankers in the Gulf of Oman, including the Barbados-flagged vessel Ocean Koi, which Iranian state media claims was attempting to disrupt its oil exports. The Iranian Navy has also intercepted vessels listed by the United States as sanctions violators, citing "violations" and threats to their oil shipments. In response, the US has disabled two ships and fired upon Iranian-flagged tankers, escalating the already tense situation. These developments have raised concerns about geopolitical risks in the oil market and highlight the ongoing struggle between Iran and the US regarding maritime control and sanctions enforcement.
