HAMBURG, Germany (AP) — A U.N.-mandated tribunal is hearing a call from Italy to order that India put on hold its case against two Italian marines pending arbitration of a dispute over a 2012 incident in which they're accused of killing two Indian fishermen.

Marines Massimiliano Latorre and Salvatore Girone are accused of killing the two fishermen while assigned to anti-piracy duty aboard an Italian oil tanker, the Enrica Lexie, off India's coast. India held the marines without charge and insists it has jurisdiction.

Italy maintains the shooting occurred in international waters, that the fishermen were mistaken for pirates and the case should be heard in an Italian court.

Arguments at the International Tribunal for the Law of the Sea are scheduled Monday and Tuesday. It wasn't immediately clear when the tribunal will rule.
