U.S. President Donald Trump says Iran was responsible for shooting down an American military helicopter near the Strait of Hormuz and that the U.S. "must" respond to the attack. Trump made the comment Tuesday in a social media post after a drone boat rescued the crew of the Apache attack helicopter that crashed near the strategic waterway, which Iran has effectively closed during its war with the U.S. and Israel. It was the first known drone rescue at sea by the U.S. military. Capt. Tim Hawkins is a spokesman for U.S. Central Command. He said the unmanned boat located the two aviators and brought them to shore.

President Donald Trump is calling for the U.S. and other oil-producing economies to pump more oil as crude prices remain volatile following U.S. strikes on Iranian nuclear facilities. The White House is also sharpening its warning to Iran against closing the Strait of Hormuz, a vital oil and gas shipping lane, in retaliation for the U.S. carrying out strikes on Iran's nuclear program. Trump in a social media posting wrote, "To the Department of Energy: DRILL, BABY, DRILL!!!" He made his call hours before Iran launched attacks on U.S. forces at Qatar's Al Udeid Air Base, its first act of direct retaliation against the U.S. after the American strikes. A U.S. defense official says no injuries were reported in the attack.
