Four people remain trapped in the Rio shopping mall, with the rescuers currently trying to reach them, Ilya Denisov, head of the Emergencies Ministry Directorate in Moscow, told TASS.

“People are behind a sealed door. We’re trying to get through to them. Firemen crawl on the floor under the cover of water from fire hoses as there’s a lot of smoke and high temperatures in the building,” Denisov said, adding that those trapped are keeping in contact via cell phones.

The fire itself covers an area of about 1,000 sq meters, according to preliminary estimates, the Emergencies Ministry press service told Interfax.

The ministry has assigned a ‘difficulty rank’ of four to the fire, the second-worst under Russian standards.

“Fifty-eight firefighting units (over 180 personnel) have been sent to the site,” its statement read, adding that rescuers are currently searching the mall for people who may have been unable to leave.

The ministry did not elaborate on the number of casualties, but confirmed that there are people injured.
