The slogan "Valls, we're waiting for you", in reference to France's prime minister, is written with tyres on A6 highway as French farmers block it access in Limonest, near Lyon, France, to protest against a squeeze in margins by retailers and food processors July 23, 2015. France announced measures worth up to 1.1 billion euros ($1.2 billion) on Wednesday to support its livestock farmers and try to halt protests which have escalated in recent days into road blockades in the northwest.
