RENO SAYS SAUDIS DID NOT COOPERATE IN BOMBING INQUIRY
Atty Gen Janet Reno criticizes Saudi Arabia for failing to cooperate in investigation into terrorist bombing last June in Dhahran that killed 19 US airmen; says Saudi Government has failed to turn over 'very important information' from investigation; her remarks mark shift for Clinton Administration after senior officials had for months praised Saudi monarchy for pledging full cooperation in inquiry; FBI Dir Louis J Freeh has complained that Saudis have provided little more than 'hearsay' that made it impossible to evaluate evidence; Freeh's and Reno's comments reflect deep antagonism within their agencies against Saudi authorities (M)
