This morning's tunnel infiltration by two Hamas squads underlines the threat posted to the south, OC Southern Command, Maj.-Gen. Sami Turgeman, said Monday. Dozens of terrorists in military uniform emerged from a tunnel, and were successfully stopped by the military, Turgeman added. Uncovering the tunnels is a complex and challenging task, requiring intelligence and technology, he added. The IDF's work in destroying tunnels, both inside Gaza and cross-border tunnels, 'is disturbing the enemy,' which spent years digging them, Turgeman said.
