The Russian Emergency Situations Ministry has planned to set up an emergency center for possible crisis in the North Caucasus Federal District, an official from the ministry said on Friday.

"A control center for crisis situations will be set up in the newly founded North Caucasus Federal District by the end of this year," Vladimir Stepanov, head of the Emergency Situations Ministry's National Control Center for Crisis Situations, told Interfax news agency.

The recent bombings in Moscow and Kizlyar reflected the need for these regional emergency centers, Stepanov said.

"We are on the right track," he added.

Established in 2006, the Emergency Situations Ministry's National Control Center for Crisis Situations have already set up emergency centers in seven federal districts and each of the 83 regions of Russia.

Russian President Dmitry Medvedev established the country's eighth federal district in the North Caucasus this January.

On Monday, two female suicide bombers killed 40 in attacks on the Moscow subway system, which the authorities have linked to militants from the North Caucasus. Two days later, twin suicide bombings rocked the restive North Caucasus republic of Dagestan, killing 12 people.

The female suicide bomber who detonated herself at Moscow's downtown Cultural Park metro station has been identified as a resident of Dagestan.

Russia's North Caucasus republics, particularly Chechnya, Dagestan and Ingushetia, have been plagued by violence, particularly against law enforcement officers, which local rebels see as representing the Russian authorities.
