Deadly Blast Still a Mystery

Police searching through the ruins of a Moscow police station which collapsed after a mysterious explosion Wednesday found two more bodies Thursday, but were still unable to determine the cause of the blast, a spokesman at the Public Prosecutor's Office said.

The prosecutor investigating the incident, who declined to be named, said in an interview that a total of six people had been killed and 35 injured when a two-story police station on Sormovskaya Ulitsa, in southeast Moscow, had been practically destroyed by an explosion.

"We still do not know the cause of the explosion, but I do not see any evil intent in what has happened," he said, adding that "the epicenter of the explosion was in the basement."

The Associated Press reported that the cause may have been a burning cigarette, but a criminal attack was not ruled out.

The prosecutor said the explosion had occurred at 5.45 P.M. when there were a lot of people on the second floor of the police-station passport department.

"The floor collapsed, burying men and women in rubble," he said, adding that two victims were still under the ruins of the building but that there was no hope that they were alive.

According to a duty officer at the police station, there were three explosions altogether. The second and third blast occurred some time after the first when rescue workers had already arrived on the scene.
