According to an eyewitness, there are no people near the bridge linking the Uzbek and Kyrgyz parts of the town at the moment.
About 1,000 people gathered at a rally on Saturday demanding to release their leaders detained by Uzbek authorities some days ago as suspects of organizing public disorders in Karasu on May 13-14.
The wife of one of the detainees poured gasoline over herself and her four kids threatening to set fire unless her husband is released.
Public disorders spread to Karasu from neighboring Andizhan on May 14.
In the small hours of May 13 militants seized the prison and a number of administrative buildings in Andizhan. The troops entered the city later and released the buildings.
According to official data, ten people were killed in the turmoil.
However, foreign news agencies reported about hundreds of victims referring to medics and human rights advocates.
The situation in Andizhan has been stabilized. Markets and state institutions are functioning normally, the press service of Uzbekistan's president told RIA Novosti on Saturday.
Some media report provocative false information about the alleged instability in this city, the press service said.
Chairman of the Russian State Duma committee for CIS and compatriots affairs Andrei Kokoshin also reported about the stable situation in Andizhan on Friday. He visited this city on his way from Osh (Kyrgyzstan) to Tashkent (the Uzbek capital).
The situation in the city is stable and life is normal, Kokoshin said.
