The @article entry type is definitely the right one for citing newspaper articles.
As you can read in the biblatex manual:
article
An article in a journal, magazine, newspaper, or other periodical which forms
a self-contained unit with its own title. The title of the periodical is given in
the journaltitle field. If the issue has its own title in addition to the main
title of the periodical, it goes in the issuetitle field. Note that editor and
related fields refer to the journal while translator and related fields refer
to the article.
Required fields: author, title, journaltitle, year/date
Optional fields: translator, annotator, commentator, subtitle,
titleaddon , editor , editora , editorb , editorc , journalsubtitle ,
issuetitle, issuesubtitle, language, origlanguage, series,
volume, number, eid, issue, month, pages, version, note, issn,
addendum, pubstate, doi, eprint, eprintclass, eprinttype, url,
urldate
Fields can be different if you don't use biblatex, but the concept is the same.
