The rally was followed by an oath taking ceremony in which nearly 500 people including women and children pledged to fight against the project till the “last blood.”

PPSS President Abhaya Sahu asked his cadres to fight the multi-national and vowed to “retaliate” the attack Thursday on its activists by “project supporters” at Dhinkia village.

“We will retaliate the attack on our supporters”, Sahu told PTI adding that the government should be held responsible for the eventualities at Dhinkia village.
