Israel hit Iran with three waves of attack, focusing on 'missile manufacturing facilities' it claimed were used to produce the missiles that Iran fired at the Jewish nation on October 1.

It also struck 'surface-to-air missile arrays and additional Iranian aerial capabilities, that were intended to restrict Israel's aerial freedom of operation in Iran,' the IDF announced.

But if Iranian officials were to strike back, Israel would be 'obligated to respond,' Rear Adm. Daniel Hagari warned in a video posted to X.

'Our message is clear: All those who threaten the state of Israel and seek to drag the region into a wider escalation will pay a heavy price,' he said. 'We demonstrated today that we have both the capability and the resolve to act decisively, and we are prepared on offense and defense, to defend the state of Israel and the people of Israel.'

IDF forces had earlier announced on social media it was conducting 'precise strikes' on military targets in Tehran in response to what it called 'the continuous attacks from the regime in Iran against Israel.'

Several hours later, the Israeli military announced that it has completed its strikes on the Iranian capital, saying: 'Our planes have safely returned home. The retaliatory strike has been completed and the mission was fulfilled.'

Israel hit Iran with three waves of attack on Saturday morning. The first focused on Iranian air defense systems, while the second and third focused on missile and drone bases as well as production sites, according to Axios reporter Barak Ravid. 

The strikes hit roughly 20 sites over the course of the night, according to the New York Times. 

Iranian officials later said those strikes caused only 'limited' damage, claiming 'the attack has been successfully intercepted and countered' by Iran's 'integrated air defense system,' its state-run news agency IRNA reported. 

It had earlier said that several 'loud explosions' that were heard across the city were related to the country's air defense systems.
