The number of ships in the Middle East is now roughly equal to that sent to the Caribbean ahead of the stunning US operation to seize Venezuelan leader Nicolas Maduro, which American forces carried out at the beginning of the year.

A US official on Wednesday put the total number of US ships in the Middle East at 10. The figure includes the USS Abraham Lincoln aircraft carrier group, which boasts three destroyers and F-35C stealth warplanes.

There are also six other US warships operating in the region -- three destroyers and three littoral combat ships.

"A massive Armada is heading to Iran," Trump posted on his Truth Social platform Wednesday, saying: "Like with Venezuela, it is, ready, willing, and able to rapidly fulfill its mission, with speed and violence, if necessary."

"Time is running out," he added, urging Tehran to "MAKE A DEAL!"

Tehran's mission to the United Nations hit back, saying in a post on X that the country "stands ready for dialogue" but "IF PUSHED, IT WILL DEFEND ITSELF AND RESPOND LIKE NEVER BEFORE!"

The carrier and its accompanying ships were ordered to the Middle East as Iran cracked down on protests that were initially driven by economic grievances, but which turned into a mass movement against the Islamic republic.

The clerical leadership that took power after the 1979 Islamic revolution responded to the demonstrations with deadly force and has held onto power, with many opponents of the system looking to outside intervention as the most likely driver of change.

Trump had repeatedly warned Iran that if it killed protesters, the United States would intervene militarily, and also encouraged Iranians to take over state institutions, saying "help is on the way."

He pulled back from ordering strikes earlier this month, saying Tehran had halted more than 800 executions under pressure from Washington, but has since renewed threats against Iran.
