The death toll from an explosion at a residential building in Russia's southern city of Shakhty has risen to four after more bodies were found under the debris, officials say.
The Emergency Situations Ministry said rescue workers found two more victims on January 15, a day after a blast rocked the nine-story building.
Earlier in the day, the ministry said the body of a woman was found under the debris.
Rescue teams found the first victim's body earlier on January 14.
One person remains missing as rescue work continues.
Investigators said they were treating the incident, in which four apartments were destroyed on the building's top two floors, as a gas explosion.
Four people were hospitalized, including a 2-year-old girl.
The blast follows a similar incident in the southern Urals city of Magnitogorsk on December 31, when an explosion sent a section of a 10-story building crashing to the ground.
Thirty-nine people died in the blast that authorities say was likely caused by a gas explosion.
