WorldFears of all-out US-Iran war return after deadly strikes escalate

Iran and the United States have exchanged their heaviest attacks since July, raising fears that their conflict could return to all-out war. Iran says the latest US bombardment killed 18 people and wounded more than 100, and accuses Washington of a war crime over a strike on a wedding in Kuhestak that killed four people, including two children. The Pentagon says it does not target civilians.
