At least two police officers were killed and another two injured in a series of two explosions, at least one of them caused by a suicide bomber, in Russia's volatile southern republic of Ingushetia, local police said on Monday.
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, but gave no details.
