Iran has warned that it could fully close the Strait of Hormuz if the United States follows through on threats to strike its power plants, escalating tensions in the ongoing Middle East conflict.
The warning came from Iran’s military operational command, Khatam Al-Anbiya, which said the waterway would remain closed until any damaged power facilities are rebuilt if such attacks occur.
The threat follows a 48-hour ultimatum from U.S. President Donald Trump demanding that Iran reopen the strait, which has been largely blocked since February 28, after U.S. and Israeli airstrikes on Iran.
Since the conflict began, Iran has responded with drone and missile attacks targeting Israel and U.S. interests across the region. The military also indicated it may strike Israel’s energy, power, and communications infrastructure, as well as facilities in countries hosting U.S. bases or companies linked to American interests.
The Strait of Hormuz, a key global shipping route responsible for about 20 percent of the world’s crude oil and liquefied natural gas supply, has seen traffic drop sharply since the outbreak of the conflict. Only a small fraction of vessels have been allowed to transit, with Iran targeting ships that ignore warnings.
Authorities have permitted limited passage for vessels from countries considered friendly, while maintaining restrictions on others. Meanwhile, Iran’s parliament is reviewing proposals to impose tolls on shipping through the strait, signaling that maritime activity may not return to pre-conflict levels soon.
