At least 48 people have died in a fire that tore through a shopping and entertainment complex in the Siberian coal-mining city of Kemerovo.
As many as 41 children may be among the victims, and 16 people are missing, Russian officials say.
The blaze started on an upper floor of the Winter Cherry complex while many of the victims were at the cinema.
Video posted on social media showed people jumping from windows to escape the flames on Sunday.
“According to preliminary information, the roof collapsed in two cinemas,” Russia’s Investigative Committee said in a statement.
The cause of the fire is not yet known and authorities have launched an investigation.
Some 660 emergency personnel were deployed in the rescue effort. Firefighters tackled the blaze for more than 17 hours.
Kemerovo, a key coal-producing area, lies about 3,600km (2,200 miles) east of Moscow.
Where did the fire start?
As well as a multiplex cinema, the shopping centre, which opened in 2013, includes restaurants, a sauna, a bowling alley and a petting zoo.
The fire is believed to have started at around 17:00 (10:00 GMT) on Sunday in a part of the building that contains the entertainment complex, local media report.
