MAKHACHKALA, November 18 (RIA Novosti) - The son of the mayor of the town of Buinaksk in the Russian North Caucasus republic of Dagestan has been kidnapped, police said Wednesday.

"At about 22:00 Tuesday, unknown assailants clad in camouflage uniforms abducted the son of the town's incumbent head Gusein Gamzatov," a police spokesman said.

The spokesman said the two men forced Gamzatov's son who was at his construction site into a Vaz-21099 car and drove away.

An investigation is underway.

Militant attacks and clashes remain common in Russia's North Caucasus, even though the Kremlin campaign to fight separatists and terrorists in Chechnya has officially ended.

Violence often spills over into nearby republics, in particular Ingushetia, Dagestan and Kabardino-Balkaria.
