I won't include the photos (that can be reached through the link above) but I will include the description of the images:
The billboard, seen below, shows 5 pictures. The picture on the top left is of a blown-up Israeli in a market after a suicide bombing. In the middle is a mutilated Israeli skull. On the top right is the picture of a wounded young Israeli soldier who was held captive. The bottom right is a picture of 2 Israelis being shot by a firing squad. On the bottom left is the picture of a member of Hezbollah holding up the severed head of an Israeli soldier at a celebration rally of the soldier's killing. On the sign in both Arabic and Hebew are the words "Beware Sharon (Israel's Prime Minister), we still have 3 of your soldiers." When the billboard was erected, Hezbollah had just kidnapped 3 Israeli soldiers (two were in their early 20s, one was 19). Hezbollah has since killed all three soldiers.
There is a UN compound near the Hezbollah bunkers where this billboard is posted.
