US President Donald Trump is escalating his verbal attack on Norway, describing it as a "dirty country". He also said that Norwegian immigrants are not welcome in America because the Nobel Committee, based in the Norwegian capital, Oslo, did not award him the Nobel Peace Prize. The Norwegian Foreign Minister, Aspen Bart Ade, said in response to the US President's comments: "Trump is fully aware that the Nobel Committee is independent. We reminded them of this and this is actually the status quo."
