Secretary of War Pete Hegseth on Wednesday confirmed that a U.S. submarine sank an Iranian warship in the Indian Ocean with a torpedo, noting it was the first time a U.S. submarine sank an enemy vessel by torpedo since World War II. Hegseth vowed continued and intensifying military pressure on Iran, declaring that the campaign was “not a fair fight” and promising sustained operations in the days ahead.

Turkey said that NATO air defenses destroyed an Iranian ballistic missile headed into Turkish airspace on Wednesday, marking the first time the alliance member has been drawn into the Middle East conflict and raising the possibility of a major expansion involving bloc allies.
