At least seven people were wounded and one was killed after an explosion ripped through a railway station in the town of Derbent in the Russian North Caucasus republic of Dagestan on Friday night, a police source said.
"According to the latest information, the number of wounded increased to seven," the source said adding that the number may rise further.
He also said that one of the hospitalized people is a police officer, who sustained grave wounds in the blast.
The explosive device was placed in a garbage dumpster near the platform where passengers were gathering to catch an intercity train.
Russia's mainly Muslim North Caucasus republics, especially Chechnya, Dagestan and Ingushetia, have seen an upsurge of militant violence lately, with frequent attacks on police and officials.
The Kremlin has pledged to wage "a ruthless fight" against militant groups but also acknowledged a need to tackle unemployment, organized crime, clan rivalry and corruption as causes of the ongoing violence in the region.
