Yahya Rahim Safavi, a close aide to Iran's Supreme Leader, said Iran has a "legitimate right" to take revenge on Israel after the attack that claimed the lives of seven members of the Revolutionary Guards.

"We have to wait to see how this will come to fruition, but the resistance front is ready," Safavi said, according to the Tasnim news agency, adding that Supreme Leader Ali Khamenei had "vowed to avenge the attack".

"No Israeli embassy is safe anymore," Safavi added.

Iran's Chief of Staff, Mohammad Bageri, also said Tehran would seek to inflict "maximum damage" on Israel, IRNA reported. "The Zionist regime's attack on the Iranian consulate in Damascus will certainly not go unanswered, and as Supreme Leader Ali Khamenei said recently, we will make the enemy regret this attack," Bageri said. "Tehran's retaliation will be carried out at the right time and with maximum damage to the enemy," he stated.

Israeli Defence Minister Yoav Gallant said after a meeting with senior officials that Israel is ready to face "any scenario that may develop".

On the other hand, a senior official in US President Joe Biden's administration said on Friday that the US was also on high alert for the risk of Iranian action targeting Israeli or American interests in the Middle East.
