The GKNB state security service said it was investigating the blast but provided no other details.
A Kyrgyz senior security officer told Xinhua that it was a suicide car bombing attack, in which the driver tried to ram the gate of the embassy compound.
The identities and nationalities of the injured are yet to be determined, he said, without offering more details.
Earlier, a Sputnik correspondent reported that ambulance cars are heading to the southern part of the city and a group of law enforcement officers had been already sent to the scene to clarify the details, while the area had also been cordoned.
