The USCIRF report says, among other things, that "incidents of religiously-motivated and communal violence reportedly have increased for three consecutive years".
"Non-governmental organisations (NGOs) and religious leaders, including from the Muslim, Christian, and Sikh communities, attributed the initial increase to religiously-divisive campaigning in advance of the country's 2014 general election.
"Since the election, religious minority communities have been subject to derogatory comments by politicians linked to the ruling Bharatiya Janata Party (BJP) and numerous violent attacks and forced conversions by Hindu nationalist groups, such as Rashtriya Swayamsevak Sangh (RSS) and Vishva Hindu Parishad (VHP).
"Christian NGOs and leaders report that their community is particularly at risk in states that have adopted 'Freedom of Religion Act(s)', commonly referred to as anti-conversion laws.
"Based on these concerns, USCIRF again places India on its Tier 2 list of countries, where it has been since 2009," the report said.
