Officers used batons to beat back stick-wielding protesters who tried to enter a police compound where three activists have been held after a scuffle Tuesday with a pro-government TV journalist.
News reports say police detained several activists and a number of protesters were injured. The opposition said its leader Levan Gachechiladze was among those injured, and his brother Georgi Gachechiladze was detained. But Interior Ministry spokesman Shota Utiashvili denied that the brother was detained.
