World Notes TERRORISM

& The explosion last April that wrecked La Belle, a West Berlin discotheque popular with U.S. servicemen, is still reverberating in Western Europe. The disco bomb killed two Americans and a Turkish woman and wounded 230 others; ten days later, following charges that Libya was responsible, President Reagan ordered bombing raids against targets in Libya. Last week West German police arrested Christine Gabriele Endrigkeit, 27, a native of West Berlin. She is allegedly an associate of jailed Jordanian Terrorist Achmed Nawaf Mansour Hazi, who has been convicted of bombing the German-Arab Friendship Society building in West Berlin a week before the La Belle blast. West German police suspected that Hazi was involved in the La Belle case, but were unable to prove it; they now believe Endrigkeit carried the bomb into the disco.
