An Egyptian security official says police have discovered 250 kilograms of explosives hidden in the Sinai desert near the border with Israel. The official says Bedouin trackers working for authorities found an underground hiding place in Nagaa Shabanah, a village a few miles south of the Rafah crossing between Egypt and the Gaza Strip. He spoke on condition of anonymity because he is not authorized to talk to media. Several anti-tank land mines were also found with the explosives. The official said Saturday that the material was to be taken across the border into Gaza. Israel has repeatedly accused Egypt of not doing enough to stop smuggling of weapons into Gaza.
