Kyrgyzstan's President Sooronbay Jeenbekov resigned on Thursday, saying he wanted to bring an end to the crisis sparked by disputed parliamentary elections earlier this month.
Protests had erupted after the election on 4 October was won by parties loyal to Mr Jeenbekov but opponents said was hit by vote-buying. The results were later annulled but this did not quell the tensions.
"I am not clinging to power. I do not want to go down in the history of Kyrgyzstan as a president who allowed bloodshed and shooting on its people. I have taken the decision to resign," Mr Jeenbekov said in a statement released by his office.
More than 1,200 people were injured and one killed during the clashes in the wake of the elections between protesters and police.
The move came as supporters of Prime Minister Sadyr Japarov - who was serving jail time for hostage-taking only last week - gathered once more Thursday to demand Mr Jeenbekov's immediate resignation.
"The current situation is close to a two-sided conflict. On the one hand, the protesters, on the other, the law enforcement agencies," Mr Jeenbekov said in the statement.
"Military personnel and law enforcement agencies are obliged to use weapons to protect the residence of head of state. In this case, blood will be shed. It is inevitable. I urge both sides not to succumb to provocations."
'Return to peaceful life'
The president had on Wednesday finally accepted the nomination of Mr Japarov as prime minister, in a move seen as the first step towards calming the crisis. But Mr Japarov insisted that the president should step down.
Mr Jeenbekov called on Mr Japarov and other politicians "to withdraw their supporters from the capital of the country so the people of Bishkek (can) return to a peaceful life."
Mr Jeenbekov had previously pledged to resign after overseeing fresh parliamentary elections in the country. But Mr Japarov and his supporters pressed for an immediate resignation.
Kyrgyzstan has been dogged by political volatility for much of its three decades of independence.
A landlocked republic of 6.5 million people, it has now seen three presidents unseated by unrest since gaining independence from the Soviet Union in 1991.
The chaos has worried its ally Russia, coming as post-election protests rock ex-Soviet Belarus and clashes persist over the breakaway Nagorno-Karabakh region of Azerbaijan.
Russian President Vladimir Putin's deputy chief of staff Dmitry Kozak flew in for talks with Mr Jeenbekov and Mr Japarov this week, with Moscow emphasising that the chaos must be brought to an end.
