How to create content type "News"
It sounds like you're off to a good start. Next, you'll need to add a new field to your content type for links to external news articles.

Home &gt;&gt; Administration &gt;&gt; Structure &gt;&gt; Content types &gt;&gt; News &gt;&gt; Manage fields

/admin/structure/types/manage/news/fields/add-field

Add a new field of type Link and label it something like News Link. Save the field.

Decide if you want to allow only one link to be saved in this field, or multiple values. Save the field settings.

Decide if you want to allow external links only in the field (the default is "Both internal and external links"). Save settings.

After that, you'll still need to make a whole bunch of decisions about how to display News content items ... but the Link field seems to be a missing link in your description.

Good luck!
