A Lebanese man charged in the 1985 TWA hijacking and the murder of a U.S. Navy diver testified Thursday he twice attempted suicide because of strife in his homeland and frustration with his life in Germany.

The trial of Mohammad Ali Hamadi entered its fourth day Thursday in a top-security courtroom of Frankfurt's Preungesheim prison.Hamadi said he was hospitalized June 14, 1983, in the German town of Saarbrucken after attempting to take his life by swallowing 10 pills. He also said under questioning he had injured his arm in another suicide attempt.

Hamadi said on both occasions he became suicidal because of his preoccupation with the situation in his native war-torn Lebanon as well as his life on welfare in Germany.
