People bring flowers to Avtozavodskaya station

Ever more flowers appear at the Avtozavodskaya metro station, in commemoration of those killed in the yesterday terrorist act, when a train car exploded.

People bring roses and carnations to the platform; flowers also lie on the parapet at the exit from the station to town. Police officers are on duty at the station and on the street near entrances to it. There are no other changes in comparison with ordinary days.

The metro explosion took place Friday at about 8:30 a.m. between the Avtozavodskaya and Paveletskaya stations. The blast epicenter was near the first left door of the second car. 39 people were killed, 113 hospitalized.

Today investigators will continue to study the circumstances of the explosion and analyze material evidence.

A source close to the investigation said the results of research conducted yesterday on the site of the tragedy might be passed today to the criminalist laboratory to specify the type of explosive.

"Having studied the nature of train damage, criminalists will be able to make a conclusion about the type of explosive and determine the substance. The power of the explosive device will also be specified," said the source. In his words, analysis of the chemical composition of the explosive can answer the question about its origin. Besides, the study results will make it possible to say whether that was a deliberate or an accidental explosion.
