SLEPTSOVOSC, Chechnya, October 26 (IslamOnline & News Agencies) - Russian military tanks have closed Saturday, October 26, the outlets of a number of Chechen refugee camps in Ingushetia. The Russian Interior Ministry has, meanwhile, declared it would apply some changes to its military operations in Chechnya.

The military has taken such measures hours after ending the hostages' crisis in Moscow that resulted in the death of 90 hostages and 50 Chechen captives.

A group of Russian soldiers, accompanied by masked members of Russian security agencies, have dug ditches around Chechen refugee camps in Federal Russia's Ingushetia Republic and refused to provide an explanation for what they did, pointing out that they had been ordered to perform such an operation, reported Agence France-Presse (AFP).

Russian tanks have cordoned off the villages of Bella, Allina, Satsita in Chechen-bordering Sleptsovosc.

Russian deputy interior minister Vladimir Vasiliev has told the Russian "Ria Novosti" news agency Saturday that Russia would apply some modifications to its military operations in Chechnya.

Vasiliev said, "Some modifications are to be applied to the work of federal forces in the separatist Chechen Republic. Tasks of police elements are to be organized," pointing out that this has nothing to do with launching new armed operations on a large scale.

Meanwhile, three Chechen fighters were killed in a Russian large-scale special operation, near Novogrozninski town, east of Grozny.

Russian federal forces leadership in Chechnya issued a statement declaring, "special forces’ units are currently combing all parts of the republic, as the information collected by their agencies revealed that groups of fighters are still there".
