In April 1988, a hostage taking took place on Ouvéa. Four gendarmes were killed and twenty-seven were held hostage in a cave by supporters of the Kanak and Socialist National Liberation Front. Twelve of the captured gendarmes were released after a while, but six members of a French anti-terrorist squad were also taken hostage. When negotiations to release the hostages did not succeed, French security forces besieged the cave and freed them. Eighteen Kanaks and two gendarmes were left dead. In the aftermath it was alleged that three Kanaks had been executed or left to die after being arrested.
