Iran Warns US: Strait of Hormuz a 'Red Line'; Will Resist Until the End

Escalating Tensions in the Gulf Region

Strait of Hormuz: A Strategic 'Red Line'

DUBAI, July 16 (Reuters) - Iran said on Thursday that the Strait of Hormuz was an inviolable "red line", warning that if U.S. President Donald Trump carried out his threat to attack Iran's infrastructure, it would strike all infrastructure across the Gulf region.

The U.S. launched a fifth night of attacks on Wednesday and reimposed a naval blockade of Iran's ports, which Washington says is aimed at reopening the Strait of Hormuz, closed by Iran last Saturday after a fragile truce collapsed.

Iran's Response to US Military Actions

After the first strikes on Wednesday night, Tehran's top negotiator Mohammad Baqer Qalibaf issued a statement saying: "We are in an essential and existential war with America".

Iranian army spokesman Brigadier General Mohammad Akraminia said on Thursday that the Strait of Hormuz, which carried about a fifth of global oil and gas shipments before the war, was a "red line" for Iran over which it maintains firm control.

"The Americans thought that by attacking some of our bases on the southern coasts of the country, they could take control of this strategic strait," Akraminia said.

"However, the Islamic Republic of Iran has the ability to exert control over the Strait of Hormuz from every single point of its territory, and this matter is never dependent on coasts and islands."

US Objectives and Iranian Resistance

Three U.S. officials told Reuters that U.S. strikes aimed at forcing open the strait are also targeting Iranian military capabilities the U.S. would want to destroy before executing more complex operations.

Iran's army earlier said in reference to the strait: "We will undoubtedly resist until the end and will neutralize American interventions in the region".

Iran's military spokesperson has said that the only way to reopen the Strait of Hormuz was for the U.S. to comply with the 14-point memorandum of understanding that the two sides signed in June, and the implementation of "Iranian regulations" regarding ship traffic in the strait.

Potential Regional Consequences

Trump on Tuesday threatened to hit Iranian power plants and bridges next week unless Tehran resumes negotiations.

Akraminia said that if Trump carried out the threat, Iran's armed forces would strike "all remaining infrastructure" across the region, and the response would be more severe, wider in scope and more destructive than previous attacks.

Iran said on Thursday it had targeted U.S. bases in Kuwait and Jordan, warning its neighbours that allowing the U.S. to launch attacks against it would not go unanswered.

Reactions from Neighboring Countries

"Our neighbours should know that providing a base to the Americans and allowing them to fire on Iranian soil is unacceptable and will not go unanswered," Iran's army said in a statement.

By early Thursday in the Middle East, sirens sounded in Bahrain, and Kuwait said it was responding to "hostile drone threats".

Iran's army said it targeted the Al Azraq Air Base in Jordan with ballistic missiles, while Iran's Revolutionary Guards said they had destroyed the satellite communications centre and early warning radar at the Ali Al Salem Air Base, as well as a U.S. military pier in the Al Shuaiba area of Kuwait.

The Bahraini Defence Ministry said the country's air defence systems had intercepted and destroyed a number of Iranian aerial attacks targeting the kingdom on Thursday.

Broader Implications and Regional Instability

Risks of Full-Scale War

The latest escalation and Iran's threats to shut off more regional energy exports and possibly strike regional infrastructure raise the spectre of a return to full-scale war in the region.

Potential for Wider Conflict

Analysts say Iran has signalled it may use its Houthi allies in Yemen to shut the Bab el-Mandeb gateway to the Red Sea, opening a new front against Washington and putting a second of the world's most vital energy arteries at risk.   

The war has killed thousands of people and displaced millions, mainly in Iran and Lebanon, where conflict restarted between Israel and Iran-backed militant group Hezbollah.
