President Vladimir Putin arrived in the Russian city of Magnitogorsk after a deadly gas explosion in an apartment building left at least 14 people dead and dozens unaccounted for, local news agencies reported.
Rescue workers have been scrambling to recover people from the rubble of the partially collapsed building. 
More than 70 are unaccounted for after the explosion.
A large section of the building collapsed after a gas explosion around 6 am local time at the high-rise in the industrial city of Magnitogorsk, nearly 1,700 kilometres east of Moscow in the Ural mountains.
Sixteen people including seven children have been evacuated.
The whereabouts of 28 people have been established but the fate of more than 70 was unclear. National television said some 50 people could be trapped under the rubble.
National television broadcast footage of rescue workers combing through mangled heaps of concrete and metal in temperatures of -18 degrees Celsius.
Temperatures in Magnitogorsk were expected to plunge to -23 degrees Celsius on New Year's night, the biggest holiday of the year in Russia.
Officials warned that two more sections of the Soviet-era high-rise on Karl Marx Street were in danger of collapsing.
Local resident Anna Koroleva told Echo of Moscow radio that the explosion shattered windows of nearby buildings.
The Kremlin said President Vladimir Putin had been "immediately notified of the tragedy in Magnitogorsk". 'Common tragedy' Located in the mineral-rich southern Ural region, Magnitogorsk, with a population of more than 400,000 people, is home to one of the country's largest steel producers.
The high-rise was built in 1973 and was home to around 1,100 people. Residents were evacuated to a nearby school.
Volunteers offered money, clothing and essentials to the victims, and some said they were ready to provide temporary shelter to those in need.
Regional governor Boris Dubrovsky said authorities planned to buy apartments for people who had lost their homes.
Staff from the local Magnitogorsk Iron and Steel Works (MMK), one of the country's largest steelmakers, took part in the rescue operation.
Billionaire Viktor Rashnikov, who controls the plant, called on city residents to help the victims.
"This is our common tragedy and pain," he said in a statement, adding that MMK would provide financial assistance to those in need.
Investigators opened a criminal probe into the accident, with the FSB security service confirming the blast had been the result of a gas explosion.
Such deadly gas explosions are relatively common in Russia where much of the infrastructure dates back to the Soviet era and safety requirements are often ignored.Source: trtworld.com
