"The Saudis in question are not accused of aiding the 21-year-old Saudi Air Force second lieutenant who killed three American sailors in the December shooting, two sources said, but some are said to have connections to extremist movements, according to a person familiar with the situation."

Extremist movements... like the fucking Saudi regime itself maybe?! We don't need "a person familiar with the situation" to tell us that. BTW anytime I read an article with unnamed sources in it I immediately doubt the content of the article.
