"It is the fundamental right of every person to live free from violence and discrimination. Authorities in Assam must take action to protect the rights of all communities and bring those responsible for the attacks to justice," the organization said.
The Assam Authorities have accused members of the Songbijit faction of the National Democratic Front of Bodoland (NDFB) for the attacks. The NDFB is an armed separatist group seeking independence for the ethnic Bodo people.
On Sunday, the Assam Police and the Indian Army killed two Bodo rebels.
Clashes between Bodo and Muslim communities took place in 2012, killing over 75 people and displacing thousands from their homes. In May 2014, the Assam authorities said that the NDFB had killed at least 27 civilians in the state.
