French police have stopped a farmers' convoy of hundreds tractors heading towards the Rungis wholesale food market south of Paris. Some 200 to 300 tractors are now sitting in the town of Sully-sur-Loire, 170 km south of Rungis. Setting off from the south-west of France at the call of union Coordination rurale, the group of angry farmers grew as they drove up the nation, with more and more joining along the way. IMAGES
