A Lebanese orphan from al-Mabarrat School sits on a destroyed tank that was used by pro-Israeli-militia at the destroyed former Israeli prison in Khiam village, south Lebanon, May 25, 2011. Lebanon on Wednesday marks the 11th anniversary of Israel's withdrawal from south Lebanon in 2000, after more than 22 years of occupation. Hezbollah, which Washington labels as a terrorist group, is largely considered the driving force behind Israel's withdrawal.
