The head of the International Atomic Energy Agency said Monday that there is a possibility of both radiological and chemical contamination within Iran's main nuclear enrichment facility in Natanz following Israeli strikes, although radiation levels outside the complex are presently normal.

IAEA director general Rafael Mariano Grossi said that the radiation poses a significant danger if uranium is inhaled or ingested. He added that the risk can be effectively managed with appropriate protective measures, such as using respiratory protection devices while inside the facilities.

Russian President Vladimir Putin and Turkish counterpart Recep Tayyip Erdogan called Monday for an "immediate" end to fighting between Israel and Iran in a phone conversation, the Kremlin said.

"The leaders called for an immediate end to hostilities and the settlement of contentious issues, including those related to Iran's nuclear program, exclusively through political and diplomatic means," the Kremlin said in its readout of the call.

Iran on Monday accused Israel of targeting a hospital in the country's west, condemning it as a "war crime".

"Farabi Hospital in the city of Kermanshah in western Iran was targeted by the Israeli regime's aggressive attacks," said foreign ministry spokesman Esmaeil Baqaei, adding that "attacking hospitals alongside attacks on residential areas is a gross violation of international law and a war crime".

France on Monday blocked access to the stands of five Israeli arms manufacturers at the Paris Air show for displaying "offensive weapons", according to a French government source.

A black wall blocked off stands run by Israel Aerospace Industries (IAI), Rafael, Uvision, Elbit and Aeronautics for showing "offensive weapons", including those used in Gaza, which allegedly violated terms made with Israel, said the source.

Russia has returned 1,245 bodies to Ukraine, Kyiv said Monday, the final stage of a deal to repatriate more than 6,000 killed soldiers that was agreed at peace talks in Turkey earlier this month.

"Another 1,245 bodies returned to Ukraine: repatriation part of Istanbul agreements has been completed," the government agency coordinating the repatriation said in a statement, with Ukraine's defense minister adding Kyiv has received more than 6,000 bodies in total over the past week.

Tens of thousands of demonstrators in the Netherlands donned red clothing and marched Sunday to protest the Dutch government's policy toward Israel, exceeding the turnout for a similar event in May.

Protesters walked a 3-mile (5-kilometer) loop around the center of The Hague to symbolically create the red line they say the government has failed to draw to halt Israel's campaign in Gaza.

President Donald Trump rejected a plan presented by Israel to the U.S. to kill Iran's Supreme Leader Ayatollah Ali Khamenei, according to a U.S. official familiar with the matter.

The Israelis informed the Trump administration in recent days that they had developed a credible plan to kill Khamenei.

Iran fired a new wave of missile attacks on Israel early Monday, triggering air raid sirens across the country as emergency services reported at least five killed and dozens more wounded in the fourth day of a conflict between the regional foes that showed no sign of slowing.

One missile fell near the American consulate in Tel Aviv, causing minor damage, U.S. Ambassador Mike Huckabee said on X. There were no injuries to American personnel.

The Iranian president on Monday urged all citizens to put aside differences and unite against Israel as conflict rages between the two arch-foes.

"Every difference, issue, and problem that has existed must be put aside today and we must stand strong against this genocidal criminal aggression with unity and coherence," Masoud Pezeshkian said, addressing parliament.

Iran's chief justice Gholamhossein Mohseni Ejei on Monday vowed swift trials for people arrested on suspicion of collaborating with Israel, as intense fighting raged between the two sides.

"If someone is arrested for having ties to and collaborating with the Zionist regime, their trial and punishment should be carried out and announced very quickly, in accordance with the law and given the war conditions," Ejei said, quoted by Tasnim news agency.
