The Kiev city administration has asked residents to delay their return to the capital city over security and humanitarian issues.
Russian forces have renewed bombardment of Kiev, the city administration said on Saturday in a statement on Telegram, urging people not to ignore the air raid sirens.
Besides, the traffic jams caused by the increased number of people, who return to Kiev, disrupt the deliveries of humanitarian aid and the work of emergency and communal services, the statement added.
Earlier on Saturday, Kiev Mayor Vitali Klitschko said one person was killed and several people were injured in a rocket strike on the city, Xinhua news agency reported.
