With nearly $315 million in damages at stake, the U.S. Supreme Court appeared divided over whether 2000 USS Cole bombing victims and their families gave proper legal notice to Sudan eight years ago.

The justices heard hourlong arguments in Republic of Sudan v. Harrison, stemming from a default judgment won by the Cole plaintiffs who claimed Sudan provided material support to al-Qaida and Osama bin Laden. The terrorist attack in Yemen killed 17 sailors and injured 42 others.
