Trump says damage to Iran's nuclear sites is 'far below ground level'

Russia warned the U.S. against providing direct military aid to Israel or even making speculative statements about it, Russian Deputy Foreign Minister Sergei Ryabkov told Interfax, Russian state media, on Wednesday.

"We caution Washington against even speculative, hypothetical options of this kind. It would be a step that would radically destabilize the entire situation," Ryabkov stressed.

"The United States is constantly at the forefront of all processes, and to say that they did not intervene before and now they will intervene, I think would be wrong," Ryabkov said, responding to a question about possible U.S. intervention in the Middle East.

Russia is also "in contact with both sides. This is happening at the working level and at the political level," Ryabkov said.

Amid President Trump's demands for an unconditional surrender and claims that Iran has asked the U.S. to continue negotiations on the unfinished nuclear deal between the two countries, the Permanent Mission of Iran to the United Nations said "no Iranian official has ever asked to grovel at the gates of the White House," in a post on X.

"The only thing more despicable than [Trump's] lies is his cowardly threat to 'take out' Iran’s Supreme Leader," the mission said.

"Iran does NOT negotiate under duress, shall NOT accept peace under duress, and certainly NOT with a has-been warmonger clinging to relevance. Iran shall respond to any threat with a counter-threat, and to any action with reciprocal measures," the mission added in the post.

The Israel Defense Forces relaxed some of the restrictions across most of Israel, but educational facilities remain closed.

Israelis can now return to their work offices, provided there is an accessible bomb shelter or safe room for employees. They can also gather up to 30 people, indoors or outdoors, the IDF said.

These relaxed rules do not apply to communities along Israel’s northern border with Lebanon, the Gaza border communities and some parts of Southern Israel.

When asked if he gave Iran an ultimatum, President Donald Trump said he gave Iran the "ultimate ultimatum," but he would not share what the ultimatum was.

Trump also said he spoke to Russian President Vladimir Putin on Tuesday, who again offered to mediate between Israel and Iran.

"I said, 'Do me a favor. Mediate your own. Let's mediate Russia first. Okay?'" Trump said Wednesday.

Trump also said that "war is very complex" and "nothing is finished until it's finished."

"I would say that we sure as hell made a lot of progress, and we'll see the next week is going to be very big," Trump said.
