Re: measure traffic from "In the News" Box
Maybe it is in google.com/news in referrals in GA? Images are in source Google and url /imgres.
Do you have news in Search Console in Search Analytics Report
We can read Search type means the type of Google search run by the user: web search, image search, video search, and so on.
I think so on if you connect with Google You Can see these information.
