A pause in Russian and Syrian strikes on Aleppo was holding for a second day Wednesday, ahead of a brief unilateral ceasefire aimed at allowing civilians and rebels to quit the devastated city. Moscow announced it would extend an eight-hour truce planned for Thursday to 11 hours and said Syrian and Russian warplanes were giving Aleppo a wide berth. At a meeting in Berlin, French President Francois Hollande said he would work with Germany to persuade Russia to adopt a long-lasting truce around Syria's second city.
