May 23 – A train hijack takes place at the village of De Punt, in the province of Groningen, the Netherlands. Activists aimed to endorse the Republik Maluku Selatan (RMS), a self-proclaimed republic in the Maluku Islands. At the same time a hostage situation occurred at a school in Bovensmilde. The Dutch Marines stormed the train at June 11, 1977, after six Starfighters flew over the train, creating a noise and distraction for the hostage takers. Six hostage takers and two passengers lost their lives in the operation. The activists at the school surrendered after they learned of the fate of their fellow activists in the train.
