It just happened in the last hour, or at least we're just hearing about it, so maybe tomorrow there will be more information.
Of course, the Lebanese government can't be expected to tell us that some of their soldiers cooperate with Hezbollah and unless someone carries an Israeli military update (doubtful), then we may never know much about it.
Although, maybe something will be in the Israeli papers and we can read their take on the whole thing.
Hi - I have read more on Lebanon's history in the last couple days than I ever thought I would. :o) There is no doubt in my mind that the Lebanese army does have some Hezbollah members. And I expect that is an open secret.
