The Emergencies Ministry said the collapse at the Saint Petersburg National Research University of Information Technologies, Mechanics and Optics took place as construction work was underway. An investigation into a criminal violation of construction safety has been opened.
St. Petersburg acting governor Alexander Beglov told journalists at the scene in the central city that 81 people were evacuated from the building.
“No victims, no injured,” he said.
He said about 20 of those evacuated were foreign students attending a weekend class.
Footage posted on social media shows people making their way through a smoke-filled corridor.
