More than 250 people were killed when a military plane crashed in a field outside Algeria’s capital on Wednesday, state media said, in the country’s worst air disaster. Television footage showed crowds and emergency vehicles massing around the smoking and flaming wreckage near Boufarik airport southwest of Algiers. A line of white body bags could be seen on the ground next to what media said was a Russian Ilyushin transport plane. A total of 257 people were killed, most of them military.
