The UK government has rejected criticism from its chief rabbi over sanctions targeting Israeli settlers, as Iran's Revolutionary Guard issued a warning to abandon tankers in the region. The warning comes after the US launched attacks on Iranian assets, escalating regional tensions. The UK's foreign office stated that the sanctions were necessary for security reasons, dismissing the rabbi's concerns as outdated. Meanwhile, Iran's military has reportedly instructed crews to leave tankers, warning that ships will be targeted if they remain. The situation has raised concerns among international shipping companies, with some fearing potential disruptions in trade routes. The UK's stance highlights the complex interplay between religious and political leadership in shaping foreign policy responses.
