Vietnamese Artillery in Laos?

Maybe this is old news. But supposedly Vietnamese artillery was at it again just a few days ago.
And there's barely a whisper anywhere in the media about it. The Straits Times doesn't say anything. Neither does the New York Times, International Herald Tribune, Times of London, Le Figaro, Le Monde, the Bangkok Post, the Vientiane Times or Xinhua. And Google News only has it somewhere down the middle. There was only news about Hmong refugees in Thailand and their repatriation. The Bangkok Post reported a statement from Vientiane relating to Hmong repatriation which would have sounded perfectly in place in the middle of Catch-22.
You'd think the fact that a foreign army was firing field artillery against alleged rebel guerillas in any country's borders would be major news. Apparently not. Apparently it's still part of the world's most secret war. Supposedly Xaisombun Special Zone, where all this bullshit is supposedly happening, doesn't even exist anymore, because it was dissolved and parceled out to the surrounding provinces in 2006. It's unreal ... and more than a little disturbing.
