The U.S. Court of Appeals for the Second Circuit on Tuesday revived a civil lawsuit accusing Saudi Arabian Al Rajhi Bank of aiding al-Qaida in carrying out the Sept. 11, 2001, terrorist attacks, and directed a lower court to conduct discovery on whether it has jurisdiction to hear the claims.

The ruling, outlined in a summary order by a three-judge panel of the Manhattan-based appeals court, came as part of a long-running multidistrict litigation in the U.S. District Court for the Southern District of New York to hold Saudi Arabia, its agents and largest Islamic bank liable for the attacks, which killed 3,000 people in New York, Pennsylvania and Washington, D.C.
