Politicians in India have protested against 'forced' conversions to Hinduism by nationalist groups. They accuse right-wing Hindus aligned with the ruling Bharatiya Janata Party (BJP) of forcibly converting Christians and Muslims, and Prime Minister Narendra Modi of doing little to stop them. The anger forced the upper house of parliament to be adjourned after rival the politicians descended into shouting matches. Al Jazeera's Karishma Vyas reports from New Delhi.
