The death toll from a fire in a Russian shopping mall has reached 56 people, the Investigative Committee, the state body that handles major crimes, said on Monday.
The Committee also said in a statement that 44 people hurt in the fire had sought medical help, and of these 10 people were still in hospital.
The fire, one of the deadliest in Russia since the end of the Soviet Union, swept through the upper floors of the mall where a cinema complex and children's' play area were located.
Russian emergency services said the fire, which started on Sunday afternoon, had now been extinguished but that rescuers were struggling to reach the upper floors because the roof of the building had collapsed.
More than a dozen people were still unaccounted for. People posted appeals on social media seeking news of their relatives or friends, and authorities set up a centre in a school near the mall to deal with inquiries from people seeking missing family members.
Russian state investigators said four people had been detained over the fire, including the owners and leasers of outlets inside the shopping mall. The Investigative Committee, which handles major crimes, said it was trying to bring in the mall's principal owner for questioning.
