A youth group is urging Russians to stop drinking Coca-Cola, in protest against sanctions the US has imposed over the Ukraine crisis. The Food Patriotism group marked the start of the school year in Moscow's Gorky Park, with placards and T-shirts proclaiming slogans such as: "For Russia, say 'no' to Cola," and "Defend our children from overseas poison." Twenty people set off metre-high fountains of Coke by mixing it with mints to cause a chemical reaction. "Imagine that happening in your kid's stomach," one activist tells Dni online newspaper.
