British Tanker Seized By Iran Is Released After 2 Months

An Iranian government spokesperson announced the release of a British oil tanker seized by Iran in July, stating that all legal and administrative procedures have been completed. The tanker was initially seized for violating maritime rules, shortly after the UK detained an Iranian tanker suspected of breaching European sanctions. Despite the announcement, the tanker remains in place, and its departure date is unclear. This development coincides with planned talks between UK Prime Minister Boris Johnson and Iranian President Hassan Rouhani at the UN General Assembly.
