This is a wildly sensationalized headline, bordering on just false.
The real story is that US government employees regularly misspell email addresses using the top-level domain .ml
(Mali) instead of .mil
(The US Military). This means that the domain administrator can read those emails. For now the administrator is some Dutch guy; the Malian government cannot read the emails.
I guess even the BBC is throwing out its last shreds of journalistic integrity at this point...
