9/11 victims' families sue Saudi Arabia: "I'm still angry"

Families of the September 11 attacks appeared in a New York court, demanding justice in a class-action lawsuit against the government of Saudi Arabia. The lawsuit accuses Riyadh of providing support to several of the 19 hijackers, which Saudi Arabia has consistently denied. The case has been ongoing for years and is one of the largest civil proceedings in U.S. history.
