January 1, 1948 saw a massacre of tribals by the police in Kharsawan city of present-day Jharkhand.

Thousands of protesters and local people had gathered there to listen to the speech of Jai Prakash Singh Munda. However, he could not reach the venue and was fired upon by the police on the restive crowd, killing hundreds. This massacre is being seen as reminiscent of the Jallianwala Bagh tragedy.
