One Palestinian was killed and another severely injured when a tunnel used for smuggling between the Gaza Strip and Egypt collapsed on them, Reuters quoted Egyptian medical and security sources as saying on Sunday. Palestinian Abdel Rahman Atieh Gomaa, 28, had fallen into a coma and was rushed to a hospital in the Egyptian coastal town of El-Arish. He had been trying to cross from Gaza into Egypt near the border town of Rafah, Egyptian security sources said. An unidentified Palestinian was also killed in the tunnel collapse, eyewitnesses said.
