BEIRUT (AP) — Kozo Okamoto, the Japanese militant who took part in a deadly attack on Tel Aviv's airport more than five decades ago, died Thursday in Beirut, the Palestinian group that had been protecting him said. The Palestinian group added that Okamoto "never compromised nor faltered but remained steadfast to his principles." The two Japanese with Okamoto were killed in the attack while he was wounded.

Japan has been demanding for years that Okamoto be handed over by Lebanon, but Beirut has repeatedly rejected the demand.
