Via Robert A. Hahn, it seems that UN troops acted as a Hezbollah intelligence service, broadcasting Israeli troop movements for them. Says The Weekly Standard:
UNIFIL–the United Nations Interim Force in Lebanon, a nearly 2,000-man blue-helmet contingent that has been present on the Lebanon-Israel border since 1978–is officially neutral. Yet, throughout the recent war, it posted on its website for all to see precise information about the movements of Israeli Defense Forces soldiers and the nature of their weaponry and materiel, even specifying the placement of IDF safety structures within hours of their construction. New information was sometimes only 30 minutes old when it was posted, and never more than 24 hours old.
Meanwhile, UNIFIL posted not a single item of specific intelligence regarding Hezbollah forces. Statements on the order of Hezbollah “fired rockets in large numbers from various locations” and Hezbollah’s rockets “were fired in significantly larger numbers from various locations” are as precise as its coverage of the other side ever got.
No wonder the IDF was having trouble winning the war! Israel needs to warn the new French-led forces, though, that if they try this again, they’re going to be treated as they deserve to be: as enemy agents at war. And mean it.
