There is a town called Yammouni, it is in the Baalbeck district of Bekaa Valley.
The USGS 1:200,000 topo shows a Younine, no Yammouni, in that area.
Same deal for various Gazetteers.
When IDF reports it, I'll believe, for now, the question mark has to remain attached.
I read an article that said Yammouni or Yammouneh is Northwest of Baalbeck... not how far though. Also read about that past history of income to Syria and Hez via heroin and weed.
