Police in Russia's North Caucasus Republic of Daghestan say they killed two suspected militants in separate incidents on June 26.
One of the suspects was killed after he reportedly opened fire at police in the republic's capital, Makhachkala.
His identity is still being determined.
Another suspected militant was killed earlier on June 26 in Daghestan's southeastern city of Derbent during a special counterterrorist operation launched on the evening on June 25.
Police say the man was wanted for participation in an illegal armed group.
Daghestan and other republics in Russia's restive North Caucasus region have been plagued by violence linked to Islamic extremism and organized crime for years, with scores of people being killed and injured.
