A freight train was derailed by a blast on a railroad in Russia's North Caucasus republic of Dagestan early on Friday, a local police spokesman said.
The bomb detonated at 05:20 Moscow time (01:30 GMT) in the republic's Karabudakhkentsky district, which borders the capital Makhachkala. The train driver and his assistant were injured.
"According to the latest information, 12 cars and the locomotive were derailed. Seven of the 12 cars were overturned," the spokesman said, adding that bomb specialists and sniffer dogs were inspecting the site of the incident.
Sporadic terrorist attacks and militant clashes are common in Russia's largely Muslim North Caucasus republics, especially Dagestan, Chechnya and Ingushetia.
A grenade on a railroad in Kabardino-Balkariya, another North Caucasus republic, was demined on Thursday, a local police source said.
Twenty-seven people were killed and 92 injured when a bomb equivalent to 7 kg (15 lbs) of TNT derailed the high-speed Nevsky Express from Moscow to St. Petersburg train in November 2009.
