The Israel Defense Forces said alerts were activated in several areas of the country after the detection of missiles launched from Iran toward Israel. The Air Force was working to intercept them, the IDF said.

The warning came on the fourth day of the conflict, when the Israeli military claimed it had achieved air superiority over the Iranian capital and could fly over the city without facing major threats.

A dramatic spike in the potential for all-out war between Israel and Iran would typically be expected to spark an immediate and strong rally in the U.S. dollar, with investors seeking the safety and liquidity of the world's reserve currency.
