On October 21, Iranian Islamic Revolutionary Guard Corps (IRGC) spokesperson Hossein Mohbi stated that Iran is preparing to launch a new weapon called "Father of All Bombs" in response to the "Mother of All Bombs" previously used by the United States. On October 22, the IRGC Navy further warned that if the United States continues its provocations, Iran might expand its countermeasures, extending targets to U.S. military bases in the Middle East. Additionally, the IRGC Navy announced on Thursday that its forces struck four vessels suspected of illegal oil transfers in the northern Persian Gulf on Wednesday, and three other vessels collided with mines west of the Strait of Hormuz.
