ARISH, Egypt (SPA) _ Egyptian police seized one ton of explosives in a mountainous zone of the Sinai Peninsula near the border with Israel, an Egyptian security official said. The explosives were discovered Friday by Bedouin nomads working as trackers for Egyptian authorities in the Rissan mountain range some 30 kilometers east of the Israeli border, said the security official. He was speaking on condition of anonymity because he was not authorized to talk to the media, the Associated Press reported.
