Brian Williams caused a Twitter uproar following comments he made during his show on Thursday about what he called "beautiful pictures" of U.S. missiles launching during an attack on a Syrian air base.

During "The 11th Hour" on MSNBC, Williams stated that the "beautiful pictures at night" of the airstrike tempted him to quote a line from a Leonard Cohen song: "I am guided by the beauty of our weapons."

He went on to call the images "beautiful pictures of fearsome armaments."

Video released by the military showed Tomahawk missiles targeted for a Syrian airfield launching from the decks of U.S. warships in the Mediterranean Sea on Thursday.

Williams was quickly mocked and criticized on Twitter for the remarks, with some users suggesting they were insensitive to the realities of war.

MSNBC didn't immediately respond to a request for comment Friday.
