Prime Minister Narendra Modi addresses rally in Jharkhand.

Prime Minister Narendra Modi today congratulated the people of Assam for "keeping away from violence" amid widespread protests against the citizenship law in the northeast. "You can easily make out who is spreading violence by the clothes they wear," he said.

"I congratulate our brothers and sisters in Assam for staying away from those who spread violence... they are making their points in a peaceful way," he said at an election rally in Jharkhand's Dumka. "The Congress and its supporters are spreading fire. When they are not heard, they spread arson," he said.
