Coverage of Diplomatic and Expulsions includes this detail: two nations declare diplomats persona non grata in escalating feud.
No separate quotation is reproduced. The rewrite keeps Diplomatic linked to Expulsions exactly as given.
Later updates on Diplomatic would need a different source than this one-line note.
