Trump said there's a good chance of making a deal with Iran.

Iran made fun of Trump's message, calling it 'helpless, nervous and stupid'.

Trump's new threat came after a US fighter jet was shot down over Iran. The second crew member was rescued safely.

The US and Iran looked for the US serviceman in a mountain area of Iran. The pilot was found soon after the plane was shot down on Friday.

This happened after a month of fighting between the US and Iran.

Iran has made it hard for ships to pass through the Strait of Hormuz. This is a very important route for oil and gas, and it's causing oil prices to rise.

Trump set deadlines for Iran to open the strait. On Sunday, he reminded them of this demand on his social media platform.

The next part of this story has strong language.

Trump said, 'If you don't open the Strait, you'll be in trouble. Open it or face the consequences.' He also said he might take over the oil if a deal isn't made.

Later, Trump told a news channel there's a good chance of making a deal on Monday.

Trump posted again, giving Iran until Tuesday at 8:00 PM to open the strait.

Trump has delayed his deadlines several times.

On March 21, Trump first threatened to destroy Iran's power plants if the strait wasn't opened within 48 hours.

Two days later, Trump said he would wait a few more days to see if talks with Iran would work. Iran said they weren't talking to the US.

As the deadline got closer, Trump delayed it again until April 6.

An Iranian official said the strait would open when they get paid for the damage caused by the war.

An Iranian general called Trump's threat 'helpless and stupid'. He said the US would face big problems if they attack.

Israel has been attacking Iranian targets and is waiting for US approval to strike more.

The US and Israel also hit an airport in Iran on Sunday.

Iran keeps attacking Israel and US allies with drones and missiles.

A building in Israel was hit by a missile, injuring four people.

A petrochemical facility in Abu Dhabi caught fire due to debris from an Iranian missile.

Kuwait said Iranian drones damaged their oil and petrochemical facilities.

Bahrain also had facilities targeted by Iranian drones.
