President Rafael Trujillo announced that Dominican troops had begun mass killings of Haitians living in the Dominican Republic.

Rafael Leónidas Trujillo Molina, nicknamed El Jefe, was a Dominican military officer and dictator who ruled the Dominican Republic from August 1930 until his assassination in May 1961. He was the 36th and 39th president from 1930 to 1938 and again from 1942 to 1952. He also served as the first generalissimo, the de facto most powerful position in the country at the time from 1930 until his assassination. Under that position, Trujillo served under figurehead presidents.

The Parsley massacre was a mass killing of Haitians living in settlements and occupied land in the Dominican Republic's northwestern frontier and in certain parts of the contiguous Cibao region in October 1937. Dominican Army troops from different areas of the country carried out the massacre on the orders of Dominican dictator Rafael Trujillo.
