Four militants were killed in a special police operation on Wednesday in the city of Khasavyurt, Russia's North Caucasus republic of Dagestan, a spokesman for the anti-terrorism committee (NAC) said.
"Four militants were killed in a shootout. Their identities are being proved. A special operation continues," the spokesman said.
On Tuesday Russian law enforcers killed another two militants in Dagestan's capital of Makhackala, involved in murders and attempts on the lives of police officers.
The NAC earlier said more than half of all terrorist attacks in the North Caucasus in 2010 occurred in Dagestan.
Russia has been clamping down on militant groups in its volatile North Caucasus republics while stepping up efforts to boost the local economies.
The Kremlin ended its decade-long antiterrorism campaign against separatists in Chechnya in April 2009, but has since had to step up the fight against militants as skirmishes and attacks on police and other officials have continued in the republic and around it.
