Welcome to the NewsHour. The U.S. Defense Secretary said today that the war with Iran has only just begun, and the war expanded once again.

Iran for the first time fired a drone into NATO territory, and the U.S. used a torpedo fired by a submarine to sink a warship for the first time since World War II.

The U.S. says it has struck more than 2,000 targets.

Iran's health ministry says more than 920 people there have been killed.
