I concur. Killing/capturing thousands of soldiers would be breaking news on major news sites/media. I just searched front page of Rt.com (favored site of LJ, gurey the addict, and conspiracy nuts) for 'yemen', 'saudi' or 'houthi', with 'Phrase not fount' results. Further search has an image like this:
You would expect captured Saudi soldiers with military attires, but those captured in the picture look like Houthis themselves.
In the conflict between Saudi Arabia & Houthis, Somalia has remained neutral, but SL has sided with Saudi Arabia and its allies including UAE.
