Luckily nobody was hurt when part of the roof and several floors of a university in Russia's second-largest city collapsed yesterday.
It happened at the St. Petersburg National Research University of Information Technologies, Mechanics and Optics while construction work was underway.
An investigation into criminal violation of construction safety has been opened.
The fifth to the second floors of ITMO University caved in, and here's the scary moment the walls started to shake:

St. Petersburg's acting governor, Alexander Beglov, told journalists at the scene that 81 people were moved out when the building was evacuated.
ITMO University is one of Russia's national research universities.
