According to Rıfat Bali, Turkish authorities bear some responsibility for the Struma disaster, killing about 781 Jewish refugees and 10 crew, due to their refusal to allow the Jewish refugees on board to disembark in Turkey. William Rubinstein goes further, citing British pressure on Turkey not to let "Struma"s passengers disembark, in accordance with Britain's White Paper of 1939 to prevent further Jewish immigration to Palestine.
