The Collective Security Treaty Organization (CSTO) does not plan to send peacekeepers to Kyrgyzstan, the head of the security body said Thursday.

Instead, the CSTO would send advisors to riot-hit Kyrgyzstan, Nikolai Bordyuzha told Interfax news agency.

"A plan is being weighed to send specialists in planning and preparing operations to prevent mass disturbances, to track down organizers and to localize criminal groups provoking tensions. But no plans are in the making to send peacekeepers to Kyrgyzstan," said Bordyuzha.

The Kyrgyz interim government's national security chief, Alik Orozov, said earlier on Thursday that Russia or Kazakhstan could make six to nine helicopters available for Kyrgyz law enforcement services.

The CSTO countries except Belarus have supported the plan to restore stability in southern Kyrgyzstan, proposed by the secretaries of the CSTO Security Council following emergency consultations. Still, Belarus pledged to approve the plan on June 17, Orozov said.

The death toll from ethnic clashes that erupted in Osh on June 11 and later in the Jalalabad region have reached 191. Over 2,000 people were wounded in the unrest.
