President Donald Trump posted a new video on Sunday, offering an update to the American people on the escalating military campaign in the Middle East.

“In the past 46 hours the United States and its partners have launched Operation Epic Fury, one of the largest, most complex, most overwhelming military offensives the world has ever seen,” Trump said in the six-minute address.

The president detailed the scale of the strikes, describing a sweeping series of attacks across Iran.
