Twenty-three Russian soldiers have died after a collapse at their military barracks in Siberia, a Russian defence ministry spokesman has confirmed.
The spokesman added that a further five troops are missing.
"All 42 soldiers who were under the rubble have been found. 23 of them are dead," Igor Konashenkov said in televised remarks.
It had earlier been reported that 18 soldiers had died.
The accident happened near the city of Omsk, at a training facility for Russian paratroopers, yesterday evening.
In footage shown on Russian television, one section of the four-storey building had completely fallen through and soldiers formed a chain to pass bricks and other debris from one to another in order to clear the mountain of rubble.
"Half of the heap has been cleared now," said acting commander of Russian paratroopers Nikolai Ignatov in remarks to Rossiya 24.
Teams of rescue workers, search dogs, and a plane with medical equipment from Moscow have been dispatched to the scene, along with military prosecutors.
A representative of the regional military investigation offices told the Interfax news agency that a probe has been launched into possible negligence.
A Kremlin spokesman said that President Vladimir Putin had been informed of the accident.
Omsk is about 2,200km east of Moscow.
According to the defence military the 242nd training centre where the accident occurred prepares junior specialists in the army, including drivers and mechanics for armoured infantry vehicles.
