An Israeli advocacy group says it has won a $323 million judgment in a U.S. court against Iran and Syria for supporting the Palestinian Islamic Jihad group that killed an American teenager and ten others in a 2006 bombing.

Washington, D.C., judge Royce Lamberth ruled, "When a state chooses to uses terror as a policy tool - as Iran and Syria continue to do - that state forfeits its sovereign immunity and deserves unadorned condemnation."

Floridian Daniel Wultz, 16, was among 11 killed when a Palestinian suicide bomber set off his explosives at a Tel Aviv restaurant six years ago.

Nitsana Darshan-Leitner of the Shurat HaDin Israel Law Center said Tuesday that the group had won courtroom victories against Iran but never before against Syria.
