Norwegian Prime Minister Jens Stoltenberg wrote Friday on his Twitter account that he had spoken by telephone with US President Barack Obama who said he was "looking forward to" picking up his Nobel Peace Prize in Oslo.
"Just congratulated Obama for a well-deserved prize," Stoltenberg said in the telegraphic style used on the microblogging site that limits entries to 140 characters.
"The president is looking forward to comimg to Oslo to pick it up," he said.
A spokesman for the prime minister later confirmed the information.
The Norwegian Nobel Committee on Friday sensationally awarded the prize to Obama less than a year after he took office, with the jury hailing his "extraordinary" diplomatic efforts on the international stage.
Stoltenberg told Norwegian media the choice was "surprising" but "exciting."
