The ⁠operation ⁠was jointly planned ⁠for ‌months with the United States ​and ‌the launch ‌date ​was decided ​weeks ​ago, an Israeli defence official told Reuters.

United President Donald Trump, confirming US’ role in the attack, said that his country had begun “major combat operations in Iran”. He claimed Iran to have continued to develop its nuclear programme and planned to develop missiles to reach the US.

The blasts occurred after an earlier strike apparently targeted an area near the offices of Iran’s Supreme Leader Ayatollah Ali Khamenei, AP reported, adding that authorities have offered no official casualty information from the strikes. According to an official quoted by Reuters, Khamenei is currently ⁠not ​in Tehran ​and has ​been ⁠transferred to a ‌secure location.

Israel’s Defence Minister Israel Katz claimed that his country has declared a state of emergency. “The State of Israel launched a pre-emptive attack against Iran to remove threats to ​the ​State of Israel,” he said.

Moreover, Israel’s ⁠military said it had protectively sounded air ⁠raid ⁠sirens in ⁠areas ‌across the ​country “to ‌prepare the public for ‌the ​possibility ​of ​missiles being ​launched toward Israel” ⁠in retaliation, as per news agency Reuters.

It announced the closure of schools and workplaces, with exceptions for essential sectors, and a ban on public airspace. Israel closed its airspace to civilian flights, and the airports authority asked ⁠the public not to go ⁠to any of the country’s airports, the report stated.
