A FRENCH association representing families of the 170 people who died in the 1989 bombing of an airliner filed suit on Wednesday against Libyan leader Moammar Gadaffi, accusing him of being an accomplice to murder. The suit by SOS-Attentats comes three months after a special French court sentenced in absentia six suspected Libyan agents to life for the bombing of the DC-10 UTA airliner. The plane exploded on September 19, 1989 over the Sahara desert in Niger while on a flight from Brazzaville, Congo, to Paris.
