Izatulla Rakhmatullaev, who heads a local Kyrgyz nongovernmental group called Justice and Legal Order, told RFE/RL that his group helped the Uzbeks reach the UN office for refugees in Osh.
The UN office has not yet commented on the information.
One of the Uzbeks told RFE/RL that he was inside the regional-administration building of Andijon during the unrest. He declined to give his name for fear of reprisals.
Some 439 Uzbek refugees had been transferred from Kyrgyzstan to Romania. Fifteen other Uzbek refugees are still in the Osh pretrial detention center.
