Ammon News - The escalation between the US and Israel on one side and Iran on the other continues on Tuesday, as the world awaits the end of the deadline given by US President Donald Trump to Iran to reach an agreement and open the Strait of Hormuz, otherwise, as he described it, “facing hell.”

New York Post newspaper reported that one of America’s “doomsday planes” was spotted circling above a key Nebraska air force base on Monday — just hours before President Trump’s deadline for Iran to accept his peace deal is set to expire.

The Boeing E-4B Nightwatch — which was designed to protect national security officials and keep the government operating in a time of nuclear war — was spotted by flight trackers above the Offutt Air Force Base, home to the headquarters of the US Strategic Command.

Israel's military announced a "wave" of air strikes on Iran after US President Donald Trump's said that a truce proposal to end the US-Israeli war on Iran from international mediators was not yet enough.

"A short while ago, the army completed an air strike wave with the aim of damaging Iranian terror regime infrastructure in Tehran and additional areas across Iran," the Israeli military wrote on its official Telegram channel.

US President Donald Trump expanded his threat against Iran to include all power plants and bridges as his ultimatum to make a deal ticked closer, after Tehran rejected a 45-day ceasefire proposal and said it wants a permanent end to the war, according to AFP.

“The entire country can be taken out in one night, and that night might be tomorrow night,” Trump said. He suggested that his Tuesday 8pm EDT deadline was final, saying he'd already given Iran enough extensions.

The US has told Iran to open the crucial Strait of Hormuz to all shipping traffic or see power plants and bridges wiped out, sparking warnings about possible war crimes.

Israel piled on pressure by attacking a major petrochemical plant and killing the intelligence chief for the paramilitary Revolutionary Guard.

Tehran with its rejection conveyed its own, 10-point plant to end the fighting through Pakistan, a key mediator, Iran’s state-run IRNA news agency said.
