Israel launched fresh missile attacks on Iran on Friday night, less than 24 hours after it hit Tehran's nuclear and military establishments, according to a BBC report.

As a result of these strikes, Iran has also activated its air defence system, Iranian state media reported.

According to Press TV, missiles were intercepted in the southern part of Tehran. The Islamic Republic of Iran Broadcasting (IRIB) also reported fresh strikes in west Tehran.

A city near Tehran, called Kara, had also been targeted, according to IRIB.

In a post on X, the Israeli Air Force said it is continuing to "attack missile launchers and infrastructure" in Iran

Earlier in the day, Israel said it conducted "preemptive" strikes on Iran, targeting its nuclear sites, further escalating tension in the region.

In an X post, IDF said: "𝐓𝐡𝐞 𝐈𝐃𝐅 𝐥𝐚𝐮𝐧𝐜𝐡𝐞𝐝 𝐚 𝐩𝐫𝐞𝐞𝐦𝐩𝐭𝐢𝐯𝐞, 𝐩𝐫𝐞𝐜𝐢𝐬𝐞, 𝐜𝐨𝐦𝐛𝐢𝐧𝐞𝐝 𝐨𝐟𝐟𝐞𝐧𝐬𝐢𝐯𝐞 𝐭𝐨 𝐬𝐭𝐫𝐢𝐤𝐞 𝐈𝐫𝐚𝐧'𝐬 𝐧𝐮𝐜𝐥𝐞𝐚𝐫 𝐩𝐫𝐨𝐠𝐫𝐚𝐦."

"Dozens of IAF jets completed the first stage that included strikes on dozens of military targets, including nuclear targets in different areas of Iran," IDF said.

IDF said Iran is inching closer to obtaining a nuclear weapon.

"Weapons of mass destruction in the hands of the Iranian regime are an existential threat to the State of Israel and to the wider world," IDF said.

IDF said: "The State of Israel has no choice but to fulfill the obligation to act in defense of its citizens and will continue to do so everywhere it is required to do so, as we have done in the past."

Speaking on the strikes, Israel PM Benjamin Netanyahu wrote on X: "This operation will continue for as many days as it takes to remove this threat."
