Schools across central Russia have been forced to close after temperatures plunged to minus 36 degrees Celsius, the Interfax news agency reported Friday.
Children in the Siberian regions of Khanty-Mansiysk, Nizhnevartovsk and Surgut have been excused from classes since the start of the week due to the extreme temperatures.
High schools have stayed open in the Tyumen, Tobolsk, Ishim, Yalutorovsk and Zavodoukovsk regions, where the weather has reached a milder 31 to 34 degrees below zero. Elementary school children are not expected to attend classes, Interfax reported.
