Iran's Supreme National Security Council must make the final decision on whether to close the Strait of Hormuz following U.S. bombing raids, Iran's Press TV said on Sunday, after parliament was reported to have backed the measure.
Iran has long used the threat of closing the Strait, through which around 20% of global oil and gas demand flows, as a way to ward off Western pressure which is now at its peak after the overnight U.S. strikes on its nuclear facilities.
The decision to close the strait is not yet final and it was not officially reported that parliament had in fact adopted a bill to that effect.
Instead, a member of parliament's national security commission Esmail Kosari was quoted on other Iranian media as saying: "For now, [parliament has] come to the conclusion we should close the Strait of Hormuz, but the final decision in this regard is the responsibility of the Supreme National Security Council."
Kosari, who is also a Revolutionary Guards Commander, had earlier on Sunday told the Young Journalist Club that closing the strait was on the agenda and "will be done whenever necessary".
Asked about whether Tehran would close the waterway, Foreign Minister Abbas Araqchi dodged the question on Sunday and replied: "A variety of options are available to Iran."
The strait lies between Oman and Iran and links the Mideast Gulf north of it with the Gulf of Oman to the south and the Arabian Sea beyond.
It is 21 miles (33 km) wide at its narrowest point, with the shipping lane just 2 miles (3 km) wide in either direction.
