Demonstrators unfurled banners calling for the tragedy to be remembered.
Authorities broke up the demonstration after about 30 minutes.
Uzbek participants said they had been warned earlier that participating in political demonstrations could affect their refugee status in Kyrgyzstan.
Other rallies marked the anniversary on May 12 in New York, Istanbul, and Kyiv. In the Uzbek capital, Tashkent, plainclothes police broke up a small demonstration by activists demanding an independent probe.

On the eve of today's anniversary, the United States joined calls for an independent probe into Andijon.
