Moscow ? An express train carrying hundreds of passengers from Moscow to St. Petersburg derailed, killing at least 39 people and injuring scores of others, emergency officials said.

The state-run railway company said the derailment late Friday could have been the result of sabotage, raising fears that the luxury train, popular with business executives and government officials, was the target of a terrorist attack.

The last three cars of the 14-car Nevsky Express left the tracks in the Tver province northwest of Moscow, the Emergency Situations Ministry said. Minister Sergei Shoigu said this morning that 39 people were dead and 18 missing.

Health Minister Tatyana Golikova told reporters at the scene that 95 people were being treated in hospitals in the Tver and Novgorod region.
