TEL AVIV, Dec. 3 (AP)—A former commander of a Jewish terrorist organization denied today that his group tried to assassinate President Truman with a letter bomb 25 years ago.

Mr. Truman's daughter, Margaret Truman Daniel, in a bioraphy of her father, said number of bombs addressed to the President and his staff had been found in the White House mail room and defused.

“I am sure the accusation by Miss Truman has no basis,” said Nathan Yellin‐More, one of the leaders of the Stern gang.

“During that period we did, however, send letters bombs, but they were all directed against the British, who were directly responsible for the situation” in Palestine, Mr. Yellin‐More said.
