Israel launched preemptive strikes against Iran amid ongoing nuclear negotiations between Tehran and Washington, triggering emergency measures domestically. The Israeli military restricted public activities while U.S. officials confirmed Washington's involvement in the operation. Eyewitnesses in Tehran reported explosions and smoke, with Iranian state media confirming an incident but withholding details. The conflict has led to airspace closures in Israel, Iran, and Iraq, with Iran threatening an 'overwhelming' response. The escalation risks regional stability and could disrupt energy markets, impacting global equities and oil prices.
