Aviation experts said Thursday that Russian air defense fire was likely responsible for the Azerbaijani plane crash the day before that killed 38 people and left all 29 survivors injured. Azerbaijan Airlines' Embraer 190 was en route from Azerbaijan's capital of Baku to the Russian city of Grozny in the North Caucasus on Wednesday when it was diverted for reasons still unclear and crashed while making an attempt to land in Aktau in Kazakhstan after flying east across the Caspian Sea. The plane went down about 3 kilometers (around 2 miles) from Aktau. Cellphone footage circulating online appeared to show the aircraft making a steep descent before smashing into the ground and exploding in a fireball. Other footage showed part of its fuselage ripped away from the wings and the rest of the aircraft lying upside down in the grass. Azerbaijan mourned the crash victims with national flags at half-staff across the country on Thursday. Traffic stopped at noon, and signals sounded from ships and trains as it observed a nationwide moment of silence.
