Ukrainian authorities are rebuilding and restoring services in the newly liberated city of Kherson, the head of the regional military administration said Saturday.

"The military administration of Kherson oblast, the military administration of Kherson city and the military administration of Kherson district have arrived in the city and have begun their duties," Yaroslav Yanushevich said in a Telegram message published on another official's account.

"The National Police and the Security Service of Ukraine have also taken up their duties. The State Service for Emergency Situations is clearing mines. We are working for the return of the city to normal life," Yanushevich said. 

About 200 police officers are currently working in the city, Ukraine's National Police said in a statement Saturday. 

"Roadblocks have been set up around and in the territory of Kherson. The regional police continue to record the crimes of the Russian occupiers," the statement reads. 

"The main threat at the moment is mass mining," and 10 groups of explosive technicians are working on the detection and disposal of explosive objects, police said. "One of the police sappers was injured today during the de-mining of an administrative building in Kherson."

Police urged "local residents to follow the established rules, to move carefully around the city and not to touch suspicious objects. If you find any, be sure to report to the law enforcement officers."

Residents who have left Kherson are advised "not to rush to return until stabilization measures are completed," police said.
