Does google news sitemap needs to be included in robots.txt - sitemap

I've read the guideline on google news sitemap but could not locate whether google news sitemap needs to be referenced on robots.txt.
https://support.google.com/news/publisher/answer/74288?hl=en#sitemapguidelines
Could someone please confirm

On the documentation page you linked, there is this note:
Once you've created your Sitemap, upload it to the highest-level directory that contains your news articles. Please see this page for further instructions on submitting your Sitemap.
It explains that you can submit the sitemaps in Google Webmaster Tools: Crawl → Sitemaps

No it does not need to be included in robots.txt if you have submitted it to Google, but it is a good practice to do so.

Symfony 2 Sitemap Google

How to tell Google that directory doesn't exist anymore?

I created health-related site based on Joomla.
I created Google Webmasters account and saw how Google indexed my site.
But then I saw that Google indexed some directory /includes (that I didn't create) and which content was far from health topics.
I deleted this directory, but already for 2 months Google Webmaster shows top keywords from /includes directory.
What should I do to tell Google that directory doesn't exist anymore?
