TEHRAN: Israel hit Revolutionary Guard sites and Evin prison in Tehran on the 11th day of the war Monday, in what it said were its most powerful strikes yet on the Iranian capital.
Iran, in turn, fired missile barrages at Israel and vowed retaliation against the United States after American strikes on the Islamic republicâs nuclear sites a day earlier.
Loud explosions rocked Tehran, where Israeli Defense Minister Israel Katz said the military hit sites with âunprecedented force,â adding to speculation that it is seeking to topple Iranâs clerical leadership.
The targets included Evin prison, which Katz said âholds political prisoners and regime opponents,â as well as command centers for the domestic Basij paramilitary and the powerful Islamic Revolutionary Guard Corps.
Iranian media and the Israeli military said Israel also struck Fordo, a key nuclear enrichment facility buried deep in the mountains south of Tehran.
The military said it had struck Fordo on Monday âin order to obstruct access routesâ to the site, which Israelâs ally the United States hit the previous day with massive bunker buster bombs.
President Donald Trump boasted that Sundayâs US strikes on three key sites had âobliteratedâ Iranâs nuclear capabilities, but other officials said it was too soon to assess the impact on Iranâs atomic program, which Israel and some Western states consider an unacceptable threat.
Sirens sounded across Israel on Monday and AFP journalists reported blasts over Jerusalem and people fleeing to shelters in Tel Aviv.
Iranian media said Israelâs strikes hit a power supply system in Tehran, triggering temporary outages.
In Israel, the national electricity company reported âdamage near a strategic infrastructure facilityâ in the south that disrupted the power supply, without naming the location or specifying the cause.
Israelâs military censorship rules bar the publication of some details about damage in Israel.
Israeli strikes on Iran have killed more than 400 people, Iranâs health ministry has said. Iranâs attacks on Israel have killed 24 people, according to official figures.
After the US strikes, global markets reacted nervously, with oil prices jumping more than four percent early Monday but dipping later in the day.
China urged both Iran and Israel to prevent the conflict from spilling over, warning of potential economic fallout.
Iranian armed forces chief Abdolrahim Mousavi said in a video statement published on state TV that Washingtonâs bombing âwill not go unanswered.â
âWe will take firm action against the American mistake,â he added.
US Secretary of State Marco Rubio called on China to help deter Iran from closing the Strait of Hormuz, a chokepoint for one-fifth of the worldâs oil supply.
The European Unionâs foreign policy chief Kaja Kallas said closing the strategic strait would be âextremely dangerous.â
With Iran threatening US bases in the region, the State Department issued a worldwide alert cautioning Americans abroad.
In Bahrain, home to a major US naval base, the US embassy said it had âtemporarily shifted a portion of its employees to local telework,â citing âheightened regional tensions.â
Meanwhile, international oil firms including BP and Total evacuated some of their foreign staff from southern Iraq, the state-owned Basra Oil Company said.
After the Pentagon stressed the goal of US intervention was not to topple the Iranian government, Trump openly toyed with the idea.
âIf the current Iranian Regime is unable to MAKE IRAN GREAT AGAIN, why wouldnât there be a Regime change???â Trump posted on his Truth Social platform.
His press secretary Karoline Leavitt said on Monday that Trump was âstill interested and engaging inâ diplomacy.
She suggested, however, that Iranians could overthrow their government if it did not agree to a diplomatic solution.
At a Pentagon press briefing, top US general Dan Caine said âinitial battle damage assessments indicate that all three sites sustained extremely severe damage.â
Speaking ahead of a NATO summit this week, the allianceâs chief Mark Rutte said Tehran should not be allowed a nuclear weapon, calling it his âgreatest fear,â while German Chancellor Friedrich Merz said âthere is no reason to criticize what America did.â
Rafael Grossi, director of the International Atomic Energy Agency (IAEA), told an emergency meeting of the UN Security Council that craters were visible at the Fordo facility, but it had not been possible to assess the underground damage.
âArmed attacks on nuclear facilities should never take place,â he added.
Iran has consistently denied seeking an atomic bomb, and Grossi has said there was no evidence to suggest it was doing so despite the Islamic republic being the only non-nuclear armed state to enrich uranium to 60 percent.
The IAEA said on Monday that Tehran had informed it of âspecial measures to protect nuclear materialâ when the Israeli campaign began.
The UN agency also said it was seeking access to Iranian nuclear sites to âaccount forâ stockpiles of highly enriched uranium.
Iranian Foreign Minister Abbas Araghchi, who met with Russian President Vladimir Putin on Monday, had accused the United States and Israel of deciding to âblow upâ nuclear diplomacy with their attacks.
