U.S. says it intercepted a surprise Iranian attack on its forces

U.S. forces intercepted what officials described as a surprise attack by Iran on American positions in the Middle East. The United States said it also struck Iran-aligned groups in Iraq in an operation carried out alongside Saudi forces.

Why this matters. It broke the strike pause that had held for two days and reset the cycle to retaliation. The Saudi participation is the notable part: it moves a Gulf state from hosting the campaign to taking part in it.
