Israel Strikes Iran, Declares State of Emergency

Israel has confirmed it carried out what it described as a “pre-emptive strike” on Iran, significantly heightening tensions in an already volatile regional landscape.

Defence Minister Israel Katz said the operation was launched in response to what he termed serious national security threats, marking one of the most direct confrontations between the two long-standing adversaries in recent years.

In an official statement, Katz announced: “The State of Israel has launched a preemptive strike against Iran.” He further declared “a special and immediate state of emergency throughout the country,” signalling the gravity of the situation and the expectation of possible retaliation. Citizens were urged to strictly follow instructions issued by Israel’s Home Front Command.

Shortly after the announcement, the Israeli military activated air raid sirens across parts of the country as a precautionary measure, warning of potential incoming missile threats. Authorities also imposed sweeping domestic restrictions, including a “prohibition on educational activities, gatherings, and workplaces.”

However, the military clarified that “essential sectors” would remain operational to maintain critical services.

Meanwhile, witnesses in Tehran reported a powerful explosion in the city centre, with thick smoke seen rising into the sky. Iranian officials had not issued an immediate response at the time of reporting, leaving questions about the scale of the damage and Tehran’s potential next move.

The strike comes against the backdrop of escalating tensions over Iran’s nuclear programme, particularly as diplomatic discussions with the United States continue.

Analysts warn that the development risks derailing fragile negotiations and could trigger a broader regional confrontation if retaliatory measures follow.
