Police in Kyrgyzstan's capital of Bishkek have used stun and smoke grenades, and water cannons to disperse protesters and have reportedly arrested those who refused to move.
According to eyewitnesses, protesters hurled stones at the police as they started to run from the square.
The move came after calls from the the protesters to start moving towards the presidential palace. Bishkek's Ala-Too Square was the site of two uprisings that saw the overthrow of presidents in both 2005 and 2010.
