In Washington, DC, no less. Didn't see coverage in the US media. I learned about this protest from Ferghana.Ru:
On August 10, 2009 the Birdamlik movement activists started open-ended hunger strike in front of Radio Liberty headquarters in Washington (District of Columbia) with the demand to cancel the censorship of Uzbek Service of Radio Liberty (Radio Ozodlik) and offer its air time for all leaders of Uzbek political opposition, residing both in Uzbekistan and abroad.

UPDATE: 73-year old Uzbek protester hospitalized.
