Hundreds of demonstrators gathered in Esquel and Trelew, 2 towns in Chubut province, against a mega-mining operation in the area that would harm the ecosystem.
The main company interested in mega-mining in Chubut was Canadian Pan-American Silver, and the bill that the governor introduced even includes uranium mining and affects the entire province.
Demonstrations were expected to be continued in the province, and in the northern larger cities as well, including Buenos Aires among other province capitals.
Protesters also gathered in Rawson, within the province, and were attacked by Argentine police, with many arrests occurring.
