So when I heard that one of the activists from there, called Prafulla Samantara was coming to Bangalore to speak about these issues, I didn't want to miss it. He described a quite scary situation, terming the actions of the government as "state terrorism". Some of the companies involved in mining in this region are POSCO (a South Korean firm), Vedanta and the Tatas.
The audience consisted of some knowledgeable and committed activists from Bangalore, including a few journalists. I took a few videos from my phone. Do watch them and share. There's also a website called OrissaConcerns.net where you can get the latest news, for example images from a solidarity rally in Bangalore last weekend.
