"From midnight, a requirement has been introduced to wear masks, to organize jobs remotely, if possible, to limit the number of participants in events in Oslo and a number of other communes," RIA Novosti quotes the minister.
According to her, the mask regime will be mandatory in places where it is impossible to maintain a social distance of one meter: in shops, restaurants and cafes, public transport and taxis.
It is noted that the innovations will not affect children under the age of 12 years.
Employers are required to provide employees with the opportunity to work remotely several times a week.
According to Hjerkol, the tightening of restrictions will affect about 22 communes where there is a risk of the spread of the omicron strain.
White House spokeswoman Jen Psaki previously said authorities would consider imposing additional restrictions on air travel due to the new strain of coronavirus.
