Il drone americano abbattuto ieri dall’Iran ha ricevuto “ripetuti avvertimenti radio” di non entrare nello spazio aereo di Teheran. Lo ha scritto l’ambasciatore iraniano alle Nazioni Unite, Majid Takht-e Ravanchi, in una lettera inviata al segretario generale dell’Onu Antonio Guterres per riferire i dettagli dell’accaduto. Per Teheran, il velivolo era “impegnato in una chiara operazione di spionaggio”.
