Lawyers for families of Sept. 11 terrorist-attacks victims have asked a New York federal appeals court to restore Saudi Arabia as a defendant in a lawsuit.

The appeal, filed Thursday with the 2nd U.S. Circuit Court of Appeals, asks the court to reverse a lower-court judge's ruling in August.

Attorney Jerry Goldman says the appeal was filed on behalf of nearly 3,000 families who lost loved ones Sept. 11, 2001, as well as others who were injured.

He says a Manhattan judge was wrong to conclude that claims in the lawsuit lacked sufficient support and that Saudi Arabia was protected by sovereign immunity.

Lawyers for Saudi Arabia did not immediately return a message seeking comment.
