An Egyptian security official said border guards discovered seven underground smuggling tunnels at the Gaza border. The official said that some of the tunnels, found north of the Rafah crossing between Egypt and Gaza, were used to pump fuel to the Gaza Strip. The official also said that police found "eleven stacks" of hashish separately near the volatile border. Smugglers had fled and left the drugs behind. Police also came across an ammunition and arms cache left over from the 1967 war near the town of el-Hassana in central Sinai. The official, who supervised the operations, said the finds were made Tuesday and Wednesday. He spoke on condition of anonymity as he was not authorized to talk to the media.
