U.S. Secretary of State Mike Pompeo expressed outrage during a meeting with Egyptian President Abdel Fattah al-Sisi over the "pointless and tragic death" of detained U.S. citizen Moustafa Kassem in Egypt, a U.S. official said on Sunday. The United States on Monday confirmed the death of Egyptian-American Kassem in a prison in Egypt, where he had been in custody since 2013, and vowed to continue to raise concerns over Cairo's human rights record.
