“We maintain that arbitrary killing is not a solution to political problems,” the statement said, adding that “justice must be seen to be done.”

The statement, prepared at the direction of Omar bin Laden, a son who had publicly denounced his father’s terrorism, was provided to The New York Times by Jean Sasson, an American author who helped the younger Bin Laden write a 2009 memoir, “Growing Up bin Laden.” A shorter, slightly different statement was posted on a jihadist Web site Tuesday.

Omar bin Laden, 30, lived with his father in Afghanistan until 1999, when he left with his mother, Najwa bin Laden, who co-wrote the memoir. In the book and other public statements, the younger bin Laden denounced violence of all kinds, a stance he repeated in the sons’ statement to The Times. None of Osama bin Laden’s sons other than Omar was named in the statement, so it was unclear exactly who else had approved the message.
