Norwegian Prime Minister Jonas Gahr Støre said that it is possible to close the border with Russia "if necessary," UNN reports with reference to TV 2.
Finland is closing all but one border crossing with Russia, and Estonia also accuses Russia of helping migrants to the border.
Störe was asked whether it is appropriate to follow the example of the Finns and close the border with Russia.
"If necessary," he replied.
Støre indicated that the Norwegian side is closely monitoring the situation in both Finland and Estonia.
