Philippine Nobel Peace Prize winner Maria Ressa arrives at Oslo airport on a trip to collect the award in person. Ressa, a journalist and an outspoken critic of Philippine President Rodrigo Duterte, and Russian journalist Dmitry Muratov were named in October as the winners of this year's award for their efforts to "safeguard freedom of expression". She is on bail pending an appeal against a conviction last year in a cyber libel case, and was required to apply to four courts for permission to pick up the prize in person. SOUNDBITE
