Explosion at Iran's Parchin Site Amid Tensions

There was a big explosion at a military and nuclear site in Iran called Parchin.

The IRGC, which is like Iran's military, said it happened.

No one knows what caused the explosion yet.

This comes at a time when there are a lot of tensions between the US and Iran.

The US has sent a big aircraft carrier and some other ships to the Middle East to help keep the area safe.

This is because Iran has been cracking down on people who are protesting.

The protesters are upset about the country's economic problems and some leaders.

The US president has said that the ships are there just in case they need to use them.

He has also said some things about Iran that Iran says are not true.
