As Israel pounds Iran with airstrikes targeting military facilities and its nuclear sites, officials in Tehran have proposed a variety of steps the Islamic Republic could take outside of launching retaliatory missile barrages.

Those proposals mirror those previously floated by Iran in confrontations with either Israel or the United States in the last few decades. They include disrupting maritime shipping through the Strait of Hormuz, potentially leaving the Nuclear Nonproliferation Treaty and attacks by allied militants.

Iran’s ambassador in Geneva derided as “hostile” and “unwarranted” U.S. President Donald Trump’s comments calling for Iran’s “unconditional surrender.”

Ambassador Ali Bahreini told reporters the Israeli campaign “has not been able to bring big damage to our nuclear facilities” because it had taken precautions to protect them.

Iran's supreme leader Ayatollah Ali Khamenei said Wednesday the nation would never surrender as demanded by President Donald Trump and warned the United States it would face "irreparable damage" if it intervenes in support of its ally.

The speech came six days into the conflict, with Trump demanding Iran's "unconditional surrender" while boasting the United States could kill Khamenei and fueling speculation about a possible intervention.

The United States is setting up a round-the-clock task force to help Americans in the Middle East during the Israel-Iran conflict, officials said Tuesday.

U.S. President Donald Trump met his National Security Council on Tuesday to discuss the Iran-Israel war, the White House said, as the U.S. leader considered whether to join Israel's air campaign against Tehran.

Israel said it struck a nuclear site near Tehran on Wednesday, while Iran said it fired hypersonic missiles as the arch foes traded fire for a sixth day.

Hours after U.S. President Donald Trump demanded Iran's surrender, supreme leader Ayatollah Ali Khamenei vowed his country would show "no mercy" towards Israel's leadership.

U.S. President Donald Trump met with his national security team in the White House Situation Room on Tuesday to make decisions about U.S. policy towards the war between Israel and Iran, three U.S. officials told U.S. news portal Axios.

U.S. President Donald Trump dramatically stepped up his rhetoric against Iran's supreme leader Tuesday, saying on social media that the United States knows where Ayatollah Ali Khamenei is located but will not kill him "for now."

In another post, Trump also appeared to demand Iran's "UNCONDITIONAL SURRENDER!" as he fueled questions about whether the United States would join Israel's attacks on Tehran's leadership and nuclear facilities.

Iran has banned government officials and their bodyguards from using all communication devices linked to the networks. The ban, announced Tuesday, includes mobile phones, smart watches and laptops.

Iran did not elaborate on the reason for the ban, which was reported by the semiofficial Fars news agency. However, it suggests Iran suspects Israel used digital signatures from electronics to launch its strikes, which have decimated Iran’s military leadership.

Since Israel launched a barrage of strikes on Iran last week and Iran retaliated with missile and drone attacks against Israel, neighboring countries have been in the flight path.
