Three Danish MPs say Nauru has blocked them from taking part in a visit to a detention centre where Australia sends asylum-seekers.
Johanne Schmidt-Nielsen, Jacob Mark and Naser Khader were scheduled to go on a two-day visit to the Pacific island nation of Nauru with other members of the Danish Parliament's Immigration Committee.
Schmidt-Nielsen suggested on Tuesday on Facebook that she and Mark were blocked because they are left-wing lawmakers who have criticised Australia's offshore asylum detention policy.
She said it's anyone's guess why Khader, "without having criticised Nauru or Australia", was also excluded.
Khader, a conservative politician originally from Syria, wrote in a separate Facebook post that he had no idea why he was blocked and "hope it doesn't have anything to do with my name and place of birth".
