Police said it was a "terrorist attack" -- Israel's term for a Palestinian strike.
Jeffrey Goldberg has a nice article about this phrase.
But the exact same phrase was used in reports by CNN (since changed,) Sky News (since changed) and the Daily Mail (also since changed.) In none of those articles was Reuters credited. (Of course, many, many news sites still have the original Reuters report with that phrase, but they at least credit Reuters.)
Not that we needed any more evidence of how lazy many reporters are, but to plagiarize an already offensive sentence is really something.
