On 3 January 2012 Iran's army chief Ataollah Salehi warned "We recommend to the American warship that passed through the Strait of Hormuz and went to Gulf of Oman not to return to the Persian Gulf". However, this was later denied by the Defense Minister of Iran. The warship is believed to be the American aircraft carrier which recently vacated the area as Iran conducted a 10-day naval exercise near the Strait of Hormuz. Salehi was also quoted as saying "We have no plan to begin any irrational act but we are ready against any threat." The US Navy responded that it will continue with its regularly scheduled deployments, in accordance with international maritime conventions.
