I used the Flym RSS client to find feeds because it has a search function. So I collected some in that app and export/imported into Feeder as an OPML.

I know it’s not exactly answering your question. If you are just wanting to get a sense of what’s happening outside the US, BBC, al jazeera etc are basic. They are all biased.

There are directories like https://feeder.co/discover/news to get you started. But if you want less mainstream stuff, then the best thing is to check out some forums/comms where the kind of news you are interested is being shared and go to the publisher site. Most have RSS but it isn’t always advertised so sometimes you have to hunt around for the feed URL.
