Donald Trump, the President of the United States, in his latest response to the protests in Iran, described the situation in the country as "critical" and announced that protesters have taken control of some cities; cities that, according to him, "nobody expected just a few weeks ago."

He added that the U.S. government is monitoring developments in Iran "carefully" and warned: "If they start killing people again, we will take action and target places that will be very painful for them," explaining that any potential U.S. action would not include "ground forces."

Trump further noted, referring to the Obama era, that there had been "retreats" in similar cases, but described what is currently happening in Iran as "incredible" and "remarkable." He accused the Iranian government of "mistreating the people" and stated that it is now "paying the price."

In conclusion, Trump emphasized that Washington is "fully" monitoring the situation in Iran and it remains to be seen "what will happen next."
