An Egyptian police official said Saturday that boxes of ammunition, RPGs and anti-aircraft missiles have been uncovered inside a mountain in the northern Sinai peninsula. The official, who spoke on condition of anonymity because he was not authorized to talk to the media, said the weapons were to be smuggled into the neighboring Gaza Strip. The mountain is about 80 kilometers south of Rafah on the Gaza border. It has been used before as a shelter for local Islamic groups that carried out three major bomb attacks starting October 2004 in Sinai. They killed 125 people in total. The official said some 2,200 bullets, 30 anti-aircraft missiles, several sacks packed with hand grenades and automatic rifles, and RPG launchers were stored inside the mountain.
