The United Stated launched military strikes and "major combat operations" against Iran on Feb. 28, President Donald Trump said, targeting the country's missile capabilities.
"Our objective is to defend the American people by eliminating imminent threats from the Iranian regime, a vicious group of very hard terrible people," Trump said.
"The lives of courage American heroes may be lost, and we may have casualties, that often happens in war, but we're doing this not for now, we're doing this for the future, and it's a noble mission," the president said.
Israeli forces also struck Iranian sites overnight. Explosions were heard in Tehran on Saturday.
