Settling in France, Curiel aided the Algerian Front de Libération Nationale and other national liberation causes, including in South Africa and Latin America.

In an interview with Jean Lesieur, published in the French magazine L'Express on 21 Feb 1991,[2] the latter said that the older Curiel had been influential as a communist in shaping his political views, as Blake met him as a teenager.

The revolutionary council and the free officers had many members from HADETU; the most eminent of these were Khaled Mohy el din, Yousef Sedeek and Ahmed Hamroush.

Curiel was a founder of "Solidarité", a support group for various anti-colonial and opposition movements in the Third World (in particular Africa and Latin America), such as the African National Congress (ANC).

[5] Under the chairmanship of Pierre Mendès France, they included Issam Sartawi, adviser to Yasser Arafat; and Uri Avnery and Mattityahu Peled, members of the Israeli Council for Israeli-Palestinian Peace (ICIPP).

[citation needed] On 21 June 1976, Georges Suffert published an article in Le Point reporting Curiel as the "head of the terrorist support network", connected with the KGB.
