The ministry shared video of emergency workers lifting two bloodied people onto stretchers and carrying them in the darkness out of the ruins of a building.
The ministry said previously that its workers rescued 10 people and handed them to doctors.
Reuters could not immediately independently verify any details of the report coming out of an area Russia said it annexed in 2022.
Ukrainian officials have not made any statement on the incident.
Russian foreign ministry spokesman Maria Zakharova said “dozens of civilians” were in the building at the time of the attack and that Western weapons were used.
The Russian-controlled Luhansk Information Centre said Ukraine shelled the bakery using the US-supplied high mobility artillery rocket system.
Earlier, Leonid Pasechnik, put in charge of Ukraine’s Luhansk region by Moscow, said dozens of people may be under the rubble.
