Where these stories come from

Each morning the Daily Newsletter Digest reads about fifty newsletters, groups them by theme and records an audio episode. These are the day’s most substantive stories from it, each with a direct link to the original article.

Links open the publisher’s own site, which may ask you to subscribe. The one-line summaries are ours; the reporting is theirs. A place tag links to that metro or country on this site, where the same story appears under In the news.
