President Trump sent a powerful warning to Iran in the early morning tweets.

Iran has been troubled for a long time, saying the United States has already targeted Iran's 52 targets in case Iran attacks Americans or US assets.

These points are very important to Iran and its culture, and warned of a very rapid and powerful attack.

He also stressed that the United States no longer wants a threat.

Twenty-two targets represent 52 Americans that Iran has held hostage for, he said.

Trump has identified the killed Soleimani as a "terrorist leader" who killed thousands of people, and accused Iran of being blatantly saying revenge.

In the meantime, the US military has stepped up its troops in the Middle East.

Hundreds of troops have left Kuwait fort at the Fort Bragg base in North Carolina, and the 82nd Airborne Corps says 3,500 rapid response troops will be deployed in the Middle East within a few days.

As concerns over US and Iran's all-out war have increased, Britain, Germany, France, China and Russia have been in close contact with each other to find solutions to alleviate tensions.
