The White House released new photos of President Donald Trump watching the large-scale U.S. operation striking Iran-backed Houthis in Yemen.

The strikes represent the biggest U.S. military operation in the Middle East since Trump took office, and come as the U.S. increases sanctions pressure on Iran while trying to bring it to the negotiating table over its nuclear program.

President Donald Trump announced he ordered the U.S. military to launch "decisive and powerful military action" against the Houthis in Yemen.
