Four militants and two policemen have been killed in a clash near Gudermes in Russia's volatile southern republic of Chechnya, local security officials say.
The Chechen Interior Ministry said the clash happened in Ishkhoi-Yurt, a village near Chechnya's second city.
Such incidents have become less frequent in recent months.
The republic was devastated by heavy fighting that started in 1994 when Russian troops first poured in to crush a separatist movement.
Russia supports counter-insurgency operations carried out by a militia loyal to Chechen Prime Minister Ramzan Kadyrov. Human rights activists say the force is guilty of numerous abuses.
