The Venezuelan government has announced it will expel German ambassador Daniel Kriener, ONA reports citing BBC.
A government statement declared Ambassador Kriener "persona non grata" and accused him of "recurrent acts of interference in internal affairs".
Mr Kriener was among a group of diplomats who helped opposition leader Juan Guaidó return to Venezuela on Monday by meeting him at the airport.
Mr Guaidó had defied a travel ban and was widely expected to be arrested.
