I don't want to speak on behalf of the Danish authorities, who are currently responding to the situation. So far, they haven't said that the drones were Russian, but they have said that a skilled operative was behind the incident. Who are the skilled operatives in this field? There aren't many, so it might be Russia. However, I don't want to get ahead of the Danish authorities.
In terms of whether Denmark or another entity is the target, given that drone incursions have been observed all over the place, Denmark is quite possibly not the only target.
