Because it is a news subject, not an academic subject, it is recommended not to mark it.

If you mark: you can mark the reference in the comments, or you can mark it in the reference:

When commenting, put the numbers ([1], [2], [3] ...) at the back of the quoted article (superscript format), and then insert the note with a label. When inserting, write clearly the source of the article.

Note in the references that you don't need to bid in the article, just write it at the back of the article. If you mean the network, you can use "z" to identify it.
