The Israel Defence Forces (IDF) reveals a Hezbollah cross-border tunnel, the last out of six that were exposed and destroyed by the Israeli army in recent months, in a guided tour on the Israel-Lebanon border. A UN peacekeeping force in Lebanon said on April 25, a tunnel discovered earlier this year by Israel had crossed the Lebanese-Israeli border, in the third such breach of a ceasefire resolution. Israel in January accused Lebanese Shiite movement Hezbollah of having dug what it described as the deepest, "longest and most detailed" tunnel it had discovered. UNIFIL said the tunnel was the third to have crossed the "blue line", a demarcation line drawn by the UN to mark Israel's withdrawal from southern Lebanon in 2000.
