 Victims of last October's attack by Hamas on Israel are now filing suit against Iran, Syria, and North Korea. They're accusing those countries of providing the militant group with some of the money, weapons, and know-how to carry out its assault. They claim the lives of around 1,200 people in Israel and precipitated the war in Gaza. The suit filed in U.S. court seeks $4 billion in damages. I'm Jack Spear, NPR News in Washington.
