We are aware of reports of UK citizens travelling to fight for the Israel Defence Force (IDF), but the Government does not estimate the numbers of those who have done so. The UK recognises the right of British nationals with additional nationalities to serve in the legitimately recognised armed forces of the country of their other nationalities. The IDF is a recognised armed force and British nationals are both able to volunteer into the IDF and eligible for national service. For Israel, one does not have to be Israeli to serve in the IDF. FCDO travel advice provides British nationals with information on the risks of travelling or living abroad, including in Israel and Occupied Palestinian Territories, and this guidance can be found on Gov.uk via the below links; Israel: https://www.gov.uk/foreign-travel-advice/israel/safety-and-security Occupied Palestinian Territories: https://www.gov.uk/foreign-travel-advice/the-occupied-palestinian-territories/safety-and-security
