Seoul summons Russian ambassador as Putin says may send weapons to North Korea

South Korea summoned Russia's ambassador to Seoul Friday to protest a defence deal signed by President Vladimir Putin and North Korea's Kim Jong Un during a visit to Pyongyang this week. Putin also said this week that Moscow did not rule out military and technical cooperation with the North, or even sending weapons -- all of which would violate rafts of UN sanctions against Pyongyang. France 24’s Douglas Herbert takes a look at the fallout from Putin’s comments.
