I searched for news about a recent event in Switzerland. I speak french, so I switched the news to ch_fr (https://kagi.com/news?q=blatten&r=ch_fr) but the results, while relevant, were mostly swiss german.
.
For the same search on the main page (https://kagi.com/search?q=blatten&r=ch_fr) the results were in swiss french as expected.

I expect the News results to focus on combination of location and language I select, similar to what the main search page does.
