JERUSALEM/WASHINGTON/TEHRAN/VIENNA/DOHA - Israeli Prime Minister Benjamin Netanyahu said on Thursday that Iran has lost its uranium enrichment and missile production capabilities.

These were two of the three goals of the joint US-Israeli attack on Iran, and the third goal, toppling the regime, now depends on the Iranian people, he said while speaking at a press conference.

"Revolutions do not happen from the air, and there are many ground options that I will not disclose," he said.

Regarding Israel's strike on an Iranian natural gas field in the Persian Gulf on Wednesday, Netanyahu confirmed earlier remarks by US President Donald Trump that Israel had not informed the United States before the attack.

"President Trump asked us to hold off on future attacks, and we're holding it," Netanyahu said.

He also said that the US and Israel together had destroyed Iran's entire naval fleet in the Caspian Sea.

As for the duration of the ongoing war, Netanyahu said it would last "as long as necessary," adding that it would end "much faster than people think".

During the press conference, Iran launched missiles towards Israel, setting off air raid sirens across the country's north. Israel's emergency service reported no casualties.

Netanyahu's remarks came amid heightened tensions after joint US-Israeli strikes on Iran began Feb 28, prompting retaliatory attacks by Iran and its regional allies against Israeli and US interests across the Middle East. 

Iran's 'capability'

Iran retains "some capability" to attack assets of the US and its allies in the Middle East, including oil facilities, US Chairman of the Joint Chiefs of Staff Dan Caine said on Thursday.

"They came into this fight with a lot of weapons," he said at the Pentagon's press conference. "That's why we continue to be as aggressive and assertive" in striking Iranian missile and drone launch sites.

Caine further said the US military has deployed a range of weapons in the war with Iran, including A-10 Warthog aircraft to attack Iranian targets in the Strait of Hormuz, AH-64 Apache helicopters in Iraq to strike alleged Iran-aligned militia groups and help shoot down Iranian drones, and 5,000-pound bunker-buster munitions against underground storage facilities.

Also on Thursday, the Israel Defense Forces (IDF) said in a statement that its air force, under intelligence guidance, struck Iranian navy infrastructures in the Caspian Sea.

The strikes, carried out on Wednesday, included targets at the Iranian Navy port and base facilities where dozens of military vessels, including missile ships and guard boats, were stationed, it said.

Navy vessels were targeted, including missile ships, support vessels, boats, and guard ships, it said.

'Intensified retaliation' 

Meanwhile, Iran warned Thursday it would carry out more severe retaliatory strikes if the US and Israel attack its energy facilities again.

Ebrahim Zolfaghari, spokesman for Iran's Khatam al-Anbiya Central Headquarters, said in a statement published by the Islamic Revolutionary Guard Corps' Sepah News that Tehran had not sought to expand the conflict to oil infrastructure or harm the economies of friendly neighboring states.

Iranian Foreign Minister Seyed Abbas Araghchi on Thursday vowed "zero restraint" if Iranian infrastructures are struck again.

In a post on social media platform X, Araghchi said "the ONLY reason for restraint" is "respect for requested de-escalation."

"Any end to this war must address damage to our civilian sites," he added.

Bushehr plant

Iran's envoy in Vienna has asked the International Atomic Energy Agency (IAEA) to condemn the Israeli attack at Bushehr Nuclear Power Plant (NPP), calling the attack "a very grave and serious situation."

In an interview published on Thursday, Reza Najafi, ambassador and permanent representative to the United Nations and other international organizations in Vienna, told Press TV that Iran's Atomic Energy Organization chief Mohammad Eslami had sent a letter to IAEA Director General Rafael Grossi, urging him to condemn the Israeli attack at Bushehr NPP. However, this letter and previous ones from the Iranian side remained unanswered.

Israel's key oil refinery

Interception fragments from a missile launched by Iran on Thursday struck Israel's largest oil refinery in Haifa, northern Israel, causing damage, according to Israeli media.

Israel's state-owned Kan TV News reported that there was no concern about the leakage of hazardous materials. It added that one man was injured from smoke inhalation, and several vehicles caught fire at the refinery compound.
