The Foreign, Commonwealth and Development Office has updated its guidance to warn Britons against all travel to Israel amid the conflict with Iran. The FCDO website warns that “travel insurance could be invalidated” if people travel against the advice, and described the current status as a “fast-moving situation that poses significant risks”. Any UK nationals in Israel should follow advice from local authorities, the FCDO added. Last night was the most I’ve seen or felt.”The UK was in the top three nations to visit Israel last year with 80,000 tourists, behind only France and the USA. Last month the number of Britons heading to Israel more than doubled to 14,700 compared with the same month in 2024.
