Hezbollah fires rockets on Israel's Safed

All reports on the fate of Hezbollah leader Hassan Nasrallah are "unworthy of attention," IRGC-affiliated Fars News says.

"Given the current situation in Lebanon and the means of access to Nasrallah, there is no way for Western media to verify the accuracy of these reports," according to the report.

Iran has accused the United States of complicity in Israel's attack on Beirut.

"This barbaric attack has been carried out by bombs gifted by the American regime to the brigand Zionist regime," Iran's foreign ministry spokesman Nasser Kanaani said in a statement Friday night local time.

This was Iran's first official reaction to the attack.

Kanaani called the air strike a "glaring war crime" and reaffirmed Iran's "absolute support" for the Lebanese government and Resistance.

The Lebanese army has set up a security cordon around the US embassy in northern Beirut, Reuters said citing a security source.

Earlier, the UK Foreign Office urged Britons to leave Lebanon with the "next available flight".

Israel's air strike on Beirut "changes the rules of the game," Iran's embassy in Beirut posted on X.

"Once again, the Israeli regime is committing a bloody massacre, targeting densely populated residential neighborhoods", the embassy said.

"There is no doubt that this reprehensible crime and reckless behavior represent a serious escalation that changes the rules of the game and brings upon its perpetrator appropriate punishment and discipline."

No senior leader from Hezbollah was killed Israel's air strike on Beirut, IRGC-affiliated Tasnim said citing informed sources in Lebanon.

"The operation was a failure," Tasnim quoted its sources as saying.

Reuters has also said that senior Hezbollah official Hashem Safieddine is alive, citing a Hezbollah source.
