US Secretary of State Antony Blinken unexpectedly met his Russian counterpart on the sidelines of the G-20 summit in New Delhi, India, on Thursday. But minimal actual dialogue seemed to take place amid deepening global rifts. And, Romania's Prime Minister Nicolae Ciucă introduced his new adviser, Ion, an artificial intelligence assistant. Also, a multiagency assessment from US intelligence officials says it is unlikely that a foreign adversary is behind the cases of so-called "Havana Syndrome'' that has stricken American diplomats, defense officials and spies based overseas. Instead, the cases appear to have different causes, from environmental factors to undiagnosed illnesses. Plus, Nigerian author Ayòbámi Adébáyò talks about her new book, "A Spell of Good Things."
