A Greek Jew now living in Israel was quoted today as saying that he saw Kurt Waldheim beat his brother at a time during World War II when, he said, Mr. Waldheim was supervising deportation of Greek Jews to concentration camps. Mr. Waldheim was a lieutenant in the German Army. The Los Angeles Times reported today that the assertion, by Moshe Mayuni, apparently is the first public firsthand testimony in support of accusations that Mr. Waldheim committed war crimes.
