Terror attacks in Moscow, Dagestan, Ingushetia may be linked

Moscow, Apr 5 : Explosions today in Karabulak of Russian republic of Ingushetia may be a link in a chain of terrorist attacks that took place in Moscow and Dagestan last week, a security source said here.

''Undoubtedly, we are studying the possible connection between the explosions in Karabulak and Ingushetia on Monday and the previous terrorist attacks in Moscow and Dagestan,'' the source told Interfax.

''The forces trying to undermine stability may be one and the same,'' he said.

However, there were also serious differences between the recent attacks, he pointed out.

The source said the explosions in the Moscow metro were aimed against civilians while in Kizlyar and Karabulak, they were aimed against law enforcement.

''Final conclusions can be drawn only after closely studying all circumstances of the latest terrorist attacks,'' he said.

Two police officers were killed and another two injured in a series of two explosions today, at least one of them caused by a suicide bomber in Russia's volatile southern republic of Ingushetia, local police said.

It quoted an Ingush police spokesman as saying that the suicide bomber set off an explosive device when he was stopped by security guards at the gates of a police station in the town of Karabulak.

A police source said the second blast occurred just minutes after the first. No one was killed or injured in the explosion, he added.

''The suicide bomber arrived in a car and it was presumed the car was mined,'' local police said. ''All security measures were taken and as a result, the police's fears were confirmed when the car exploded,'' he added.
