Russia on Thursday warned the United States against any 'military intervention' in the Iran-Israel war, according to AFP.

"We would like to particularly warn Washington against military intervention in the situation, which would be an extremely dangerous step with truly unpredictable negative consequences," AFP quoted Russia's foreign ministry's spokeswoman Maria Zakharova as telling reporters.

The head of Russia's nuclear energy corporation warned on Thursday that an Israeli attack on Iran's Bushehr nuclear power plant could lead to a "Chernobyl-style catastrophe".

An Israeli military spokesperson said Israel had struck the site, but an Israeli military official later called this statement "a mistake" and said he could neither confirm nor deny that the Bushehr site on the cost of the Gulf had been hit.

Israel’s Defence Minister, Israel Katz earlier issued a stark warning, declaring that Iran’s Supreme Leader Ayatollah Ali Khamenei “can no longer be allowed to exist” after an Iranian missile strike hit a hospital near Tel Aviv.

Katz accused Khamenei of orchestrating a direct assault on civilians and pledged consequences. “The cowardly Iranian dictator sits in the depths of a fortified bunker and fires missiles at hospitals and residential buildings in Israel.

These are war crimes of the most serious kind — and Khamenei will be held accountable for his crimes,” he wrote on X.

On Wednesday, Iran's Supreme Leader, Ayatollah Ali Khamenei, warned that the US will "suffer irreparable harm" for interfering in its conflict with Israel.

Donald Trump has responded, saying he might strike Iran or he might not.

Addressing a press conference from the White House's south lawn, Trump spoke about whether the US will join Israel in its military offensive against Iran to ensure Tehran does not develop a nuclear weapon.

"I may do it, I may not do it - nobody knows what I'm going to do," he said.

Iran's Supreme Leader had said that his country "will never surrender" in response to Donald Trump's call for an "unconditional surrender" from Tehran's regime.

"The US President threatens us. With his absurd rhetoric, he demands that the Iranian people surrender to him. They should make threats against those who are afraid of being threatened. The Iranian nation isn't frightened by such threats," he said.

On Tuesday, Trump issued a warning to Iran's Supreme Leader, asking him to 'surrender unconditionally' and also stating that he knows where Ayatollah Ali Khamenei is hiding and can get him eliminated.

"We know exactly where the so-called 'Supreme Leader' is hiding. He is an easy target, but is safe there - We are not going to take him out (kill!), at least not for now," Trump wrote on Truth Social.

Trump said the only reason the US is choosing not to eliminate Khamenei is to avoid any retaliation against American civilians and troops.
