Boeing airliner crashes in Russia, 50 killed

(Reuters) - A Boeing 737-500 airliner crashed on landing in the Russian city of Kazan on Sunday, killing all 50 on board and highlighting the poor safety record of Russian airlines that ply internal routes across the world's largest nation.

The Tatarstan airlines flight from Moscow was trying to abort its landing in order to make a second approach, but it exploded on hitting the runway, killing all 44 passengers and six crew on board, emergency officials said.

The only picture shown from the scene on Russian television reports was a blurred still shot of the plane's fuselage with firefighters in the foreground, apparently after they had extinguished a fire at the scene.

Flight U363 took off from Moscow's Domodedovo airport at 6:25 pm (1425 GMT) and crashed just over an hour later, emergency officials said.

The plane was 23 years old.
