A passenger airplane flying from Armenia's capital, Yerevan, to the city of Sochi in southern Russia has crashed over the Black Sea, officials say. The Airbus 320 plane from Armenian Airlines was carrying about 100 people, when it disappeared from radar screens about 0215 (2215GMT Tuesday). Debris has been seen in the sea, about 6km (four miles) from the coast, says Russia's Emergencies Ministry.
