Vladimir Putin phoned Barack Obama on Thursday, their first call since February, to discuss Iran nuclear talks, "the increasingly dangerous situation in Syria" and the need to counter ISIS, the White House said.

Finland President Sauli Niinisto was reportedly "indignant" when asked about criticism of his ties to Russia amid the Kremlin's recent aggression.
