The mob which stormed the mission stole the belongings of diplomats and also carried away hard drives and documents. Since then, the large compound beside Ferdowsi street in central Tehran has been under de facto Iranian control. The mission will have to be swept for listening devices and provided with secure communications before it can be considered suitable for diplomats to resume their normal duties. At present, the entire embassy is officially regarded as “unclassified” – or unfit for sensitive work.
