Earlier today in the NYTimes, this gem of unbiased headlines:

"A U.S. Tomahawk missile hit a naval base beside an Iranian school, video shows."

While in the article:

"A newly released video adds to the evidence that an American missile likely hit an Iranian elementary school where 175 people, many of them children, were reported killed."

So:

"Evidence shows US Tomahawk Missile Killed 175 people after it hits a Iranian elementary school"

Would be more apt.
