One of the most relevant documents found is a letter dated 2021, signed by Ismail Haniyeh, head of Hamas's Political Bureau, addressed to the president of the PCPA. In the letter, Haniyeh explicitly calls for "unity" and expresses clear support for the organization, confirming its ideological and operational alignment. This support represents an official confirmation of Hamas's strategic control over PCPA's operations.
The second document is even more revealing, as it is an internal list of PCPA operatives, which includes high-ranking names directly involved in the flotillas to Gaza. Among them are Zaher Birawi, head of Hamas's sector in the United Kingdom, known for leading maritime missions over the past 15 years, and Saif Abu Kashk, a PCPA operative in Spain. Both are directly linked to the organization of the "Sumud" flotilla.
