2021 United States–Iran naval incident

Iran's Islamic Revolutionary Guard Corps stated on 25 October 2021 that they had thwarted an attempt by the United States to capture and detain an tanker carrying Iranian oil in the Gulf of Oman by carrying out a heliborne operation and directing the ship back to Iran's territorial waters. The Pentagon rejected the Iranian statement and said that Iranian forces had seized a Vietnamese-flagged oil tanker in October.
