Another update: Again thanks to dave the mad jock for a link to an interview on CBC radio with Canadian retired major general Lewis Mackenzie, discussing the death of a Canadian peacekeeper, one of four killed at the UN outpost on Tuesday, whom he knew:

We received emails from him a few days ago, and he was describing the fact that he was taking fire within, in one case, three meters of his position for tactical necessity, not being targeted. Now that's veiled speech in the military. What he was telling us was Hezbollah soldiers were all over his position and the IDF were targeting them. And that's a favorite trick by people who don't have representation in the UN. They use the UN as shields knowing that they can't be punished for it.

Update again: A few days before the tragedy, Canadian TV also received an email from Major Paeta Hess-von Kruedener, the Canadian peacekeeper now missing and presumed dead. Among other things he wrote:

What I can tell you is this: we have on a daily basis had numerous occasions where our position has come under direct or indirect fire from both artillery and aerial bombing. The closest artillery has landed within 2 meters of our position and the closest 1000 lb aerial bomb has landed 100 meters from our patrol base. This has not been deliberate targeting, but has rather been due to tactical necessity. (My emphasis.)
