There are new scenes of street violence in Kyrgyzstan.
At least two people are reported dead as authorities maintain they have reasserted control in the south of the country.
Supporters of the ousted president Kurmanbek Bakiyev had earlier attempted to seize state buildings in three cities, including Jalalabad and Osh.
The government is vowing to track down and punish those behind what it is calling a coup attempt.
Deputy head of the interim government, Azimbek Beknazarov, said: “We know who the organisers are. We know their names and where they are. We also know who supports Bakiyev among us. That is why it will take four days for us to take specific measures, and the measures will be drastic.”
The cities in the south are where Bakiyev had his power base before being ousted a month ago in violence that left dozens of people dead.
Observers are describing this latest violence as the biggest challenge yet to the interim government. It is vowing to seek Bakiyev’s extradition from Belarus to face charges including corruption.
