US cancels G20 group photo after European diplomats object to posing with Russia's Lavrov

US has cancelled a group photograph of G20 diplomats after several European representatives objected to being pictured alongside Russian Foreign Minister Sergey Lavrov and threatened to boycott the session. US Secretary of State Marco Rubio, who's presiding over the G20 Foreign Ministers' meeting, cancelled the photo, as controversy surrounding it would distract from the meeting's proceedings.
