Two passenger trains have been delayed after a bomb exploded on the rails in the Republic of Dagestan in Russia's volatile North Caucasus region, local railway officials said on Sunday.
The incident occurred in the early hours on Sunday near the Inchkhe station in Dagestan's Karabudakhkent district near the capital Makhachkala, derailing a freight train. No one was hurt in the incident.
"Repair teams have been sent to the scene of the incident and train traffic is expected to be resumed soon," the railway officials said.
Twenty-seven people were killed and 90 injured when a bomb equivalent to 7 kg (15 lbs) of TNT derailed a high-speed Moscow-St. Petersburg train, Nevsky Express, on November 27, 2009.
Last week, two suicide bombings in the Dagestani town of Kizlyar killed 12 people and left 29 others injured.
