The Palestinian Authority has anti-aircraft missiles, anti-tank missiles and Katyushas stored in the Gaza Strip for use against Israel in a more \"advanced\" stage of the Oslo war. Israel Radio Arab Affairs Correspondent Avi Yissakharov reported this morning that Israeli security sources believe that the PA would launch Katyusha attacks on nearby Israeli cities such as Ashkelon. Under the Oslo Accords, it is illegal for the Palestinian Authority to have missiles and rockets in its possession.
