The electoral authorities in Kyrgyzstan have annulled the results of parliamentary elections following violent protests.
Demonstrators broke into parliament overnight and clashed with police, demanding a new vote be held.
Hundreds were injured and one person has died, the Health Ministry said.
The move by the electoral commission came soon after President Sooronbai Jeenbekov accused "political forces" of trying to illegally seize power.
Protests broke out after only four political parties out of 16 passed the threshold for entry into parliament in Sunday's election. Three of the four have close ties to President Jeenbekov.
As well as parliament, the protesters stormed other government buildings, freeing a number of high-profile prisoners.
In a video address earlier on Tuesday, President Jeenbekov accused "certain political forces" of using the results of the election as a reason to "violate public order". "They did not obey law-enforcers, beat up medical workers and damaged buildings".
He said he had "so far... taken all the possible measures to prevent an escalation of the situation" and urged opposition parties to "calm their supporters down and take them away from areas of mass gathering".
He also said he proposed a thorough investigation of any electoral violations. A short while later the Central Election Commission said it had "invalidated the election results".
The BBC's Almaz Tchoroev, in Bishkek, said the election will now be rerun but it is not yet clear when or how it will happen.
The president remains in power and has influence but it is unclear how much influence he still has, our correspondent notes.
