Russian authorities say four rebels and one police officer have been killed in two clashes in Russia's north Caucasus region.
Officials say the officer and three rebels were killed early Sunday when authorities raided a suspected rebel camp in a wooded area in the province of Dagestan. Russia's main investigating agency, the Investigative Committee, says three local policemen were also wounded during the operation.
In a separate incident, Russian security services say one militant was killed and several others detained in the southern city of Astrakhan.
Authorities say they foiled plans by the men to carry out terrorist attacks on Monday's Victory Day holiday, which commemorates the end of European fighting in World War II.
