Re: Where was Vienna convention when Afghan Ambassador was

so-called government of Taliban was shattered, Talibans run into holes or caves - the sovereignty of the country was compromised. So hence he didn’t entitle to diplomatic immunity.

well handling over the ex-diplomat is minor issue, what do you think what happened to all the embassies of Afghanistan and it’s foreig mission around the world - who is in-charge of them?
