Tehran’s strikes on US regional allies come in response to hits on Iranian civilian infrastructure, including bridges and power facilities

The two servicemen were killed Friday as the US and partner forces defended against Iranian ballistic missile and drone attacks, according to a statement from the US military.

The strikes came as a new statement attributed to Iran’s supreme leader Mojtaba Khamenei warned of “unforgettable lessons” for the United States.
