A 20-year-old Palestinian died when he accidentally fell into one of the tunnels across the border line between Gaza and Egypt, local radio stations reported on Sunday. Subhi Al-Sousou suffered critical injuries when he fell into the 30-meter-long tunnel. He was whisked to Abu Yusuf Al-Najjar Hospital where he succumbed to his injuries. Scores of Palestinians have lost their life in such accidents inside or nearby the tunnels, used by the Gazans to smuggle various materials.
