The Supreme Court on Friday said that the families of victims of terrorist attacks in Israel may sue the Palestinian Authority in a decision that will likely make it easier for victims of other overseas attacks with ties to Palestinian groups to seek damages in US courts.

The victims had sued under the Anti-Terrorism Act, signed into law in 1992. The law was passed to open U.S. courts to victims of international terrorism, spurred by the killing of American Leon Klinghoffer during a 1985 terrorist attack aboard the Achille Lauro cruise ship.

The U.S. Supreme Court on Friday unanimously upheld a federal law that allows victims of terrorism to sue two Palestinian entities in U.S. courts.
