Spanish farmers on Friday blocked streets across the country in a fourth day of protests and announced plans to gather in Madrid as they railed against the EU's environmental rules and what they see as excessive taxes and red tape. Since Tuesday, Spanish farmers have joined peers from Germany, France, Italy, Portugal and Belgium in daily protests that include blocking several highways and ports. On Friday, traffic on the A-2 highway to Madrid near the central town of Torija snarled behind a convoy of tractors bearing Spanish flags and blaring their horns, while farmers wearing yellow vests waved baguettes from an overpass at the vehicles below.
