Moscow: Three suspected guerrilla fighters were killed in a clash with police in Russia`s turbulent Dagestan region on Friday, Russian news agencies reported.
"Three guerrilla fighters were killed in a clash (in Dagestan`s capital Makhachkala). They are being identified," RIA Novosti quoted an FSB security service official as saying.
The suspects reportedly opened fire on a police post and were repulsed by a police patrol, NTV television reported.
In a separate incident, two suicide bombers set off explosive devices "when cornered in an apartment in Chechnya`s town of Shali and asked to surrender," injuring three policemen and three locals, Russian military officials said as quoted by Interfax.
Concerns have mounted over increased militant attacks throughout Russia`s Caucasus region, where Islamist militants have been battling pro-Kremlin local authorities and Russian security forces in a low-level insurgency.
