(ANSA) - BELGRADE, FEB 25 - Farmers' protests in Serbia against the Belgrade government are intensifying and spreading, with a particular focus on protecting domestic milk production following a recent, unsuccessful meeting with the minister. The number of roads blocked by tractors has increased to around 80 since this morning. Some sections are completely blocked for 24 hours, while on others, farmers take a 60-minute break at set times (usually 2 or 3 PM) to allow vehicles to pass. According to a live blog from independent broadcaster Nova, farmers plan to block roads for 24 hours, including the Ibarska highway in Mrcajevc and near Čačak. Tractors began blocking roads on February 11. Farmers' associations have halted communication with Agriculture Minister Dragan Glamočić, citing "inaccurate and offensive" statements about farmers. According to Nova, the minister made "offensive" statements such as "the profit per cow is €4,000," that producers are "drunken millionaires" who "wear Rolex watches," and are "politicised," or that the government asked the rhetorical question "why farmers intend to continue this activity if it is not profitable." "We believe it is beneath our dignity to engage in dialogue with such a minister," the statement reads. Over 30 associations, many of which are local, have joined the mobilisation, demanding "concrete, clear, and written proposals" from the Belgrade government to protect domestic cow milk production. According to Nova's blog, police officers have begun fining tractor drivers who block roads, and as a symbolic gesture of solidarity, the retail chain Lidl has agreed to buy one million litres of milk from Serbian producers to be processed into long-life milk.
