Some article did not link back to original post but some did.
I tested on Thai Language RSS

Tested on Lao Language RSS
http://www.ifreedo.com/category/3/ข-าวลาว-laos-news
I put 3 news sources into same Category
Oh btw, if we have prefix on each news, it might be helpful for our readers to identify the news sources.
Thanks
