An Egyptian security official said Egyptian guards have discovered eight new smuggling tunnels north of the Rafah border crossing with the Gaza Strip. The official said the tunnels were found in the last 24 hours and one Egyptian smuggler was arrested Tuesday inside one of them. He said that in a separate incident, police fired at suspected smugglers in the Sinai desert near the Egyptian-Israeli border. They fled, leaving behind 1,100 pounds, or 500 kilograms, of hashish in large sacks. The official spoke on condition of anonymity because he is not allowed to talk to the media. Egyptian authorities have promised to crack down on the smugglers who use a wide network of underground tunnels between Egypt and Gaza.
