Norway will announce further restrictions this week to slow the spread of the coronavirus, Reuters quoted the government as saying on Tuesday, without giving details of the plans.

The number of cases has risen in many parts of the country, with last week's figure of 2,942 new infections setting a new record in a nation which long had one of Europe's lowest infection rates.

Last week, Norway tightened restrictions on gatherings and foreign workers entering the country.

“We can't wait and see if the measures we announced last week are enough. That is why the government will introduce additional restrictions this week. We have to take precautions,” Health Minister Bent Hoeie told a news conference.

Camilla Stoltenberg, head of the Norwegian Institute of Public Health (FHI), told the same news conference there was no sign of the surge in infections slowing.
