Russia's transport oversight agency has ordered the country's airlines to stop using Tu-154B planes until the cause of a passenger jet fire and explosion that killed three people is determined.
A spokesman for the Rostransnadzor agency, Sergei Romanchev, said airlines must obey the order.
It was not immediately clear how many of the planes are in service in Russia.
The Tu-154B is one variant of the Tu-154 model, which has been in service since the early 1970s.
No cause has been determined for the January 1 fire, which also injured 43 people. The blaze began as a TU-154B carrying 124 people was taxiing for takeoff at the airport in Surgut, about 2,100 kilometers east of Moscow.
