The Iranian military announced the death of two more soldiers after last night’s raids, bringing the total number of dead to four, according to the BBC.

In a post on messaging app Telegram, the Islamic Revolutionary Guard Corps (IRGC) said Sajjad Mansouri and Mehdi Naghavi, both members of Iran’s military, were killed in addition to the two soldiers announced earlier.

Earlier, Iran’s Tasnim news agency reported that two Iranian soldiers were killed during airstrikes on the S300 artillery fire control center in a suburb of Tehran.

“The army of the Islamic Republic of Iran, defending the security of Iran and the interests of the people and Iran, sacrificed two of its fighters while facing the missiles of the criminal Zionist regime,” the army said in a statement.

The strike against the S300 artillery was in the first wave of the Israeli attack.

The first explosions were heard at approximately 02:15 (local time, 01:45 Greek time), mainly west of Tehran, as reported by the Iranian news agency Irna.

Israel “attacked military centers in the provinces of Tehran, Khuzestan (southwest) and Ilam (west),” which border Iraq, “as part of a de-escalation operation,” Iran’s air defense forces said in a statement.

According to the same source, the Israeli attack caused “limited damage in some areas”.

Iranian state television had spoken during the night of “six powerful explosions” around Tehran, which were linked “to the activation of the anti-aircraft defense system.”

Iran announced the suspension of all flights in its airspace until further notice, but air traffic has now been restored.

“No explosion or fire” has been reported at Tehran’s central refinery, the Tasnim news agency said.
