In 1969, an unorganised strike on the Antillean island of Curaçao resulted in serious disturbances and looting, during which a part of the historic city centre of Willemstad was destroyed by fire. Order was restored by Dutch marines. In the same year, Suriname saw serious political instability with the Surinamese prime minister, Jopie Pengel, threatening to request military support to break a teachers' strike.
