Officials say an airliner has crashed in Russia, killing all 50 people aboard.
It happened as the Boeing 737 belonging to Tatarstan Airlines attempted to land in the city of Kazan (kah-ZAHN'), about 450 miles east of Moscow.
The Emergencies Ministry says the dead included the son of Tatarstan's governor and the head of the Tatarstan branch of the Federal Security Service, the main successor agency to the Soviet-era KGB.
Reports say the plane appeared to lose altitude as it was making a second landing attempt, then crashed and caught fire.
A journalist who said she had flown on the same aircraft from Kazan to Moscow earlier in the day told Channel One state television that the landing in Moscow had been frightening because of a strong vibration during the final minutes of the flight.
Russia has seen a string of deadly crashes in recent years. Some have been blamed on the use of aging aircraft, but industry experts point to a number of other problems, including poor crew training, crumbling airports, lax government controls and widespread neglect of safety.
