evidence: Tensions were high Wednesday in the western Indian city of Udaipur, a day after police arrested two Muslim men accused of slitting a Hindu tailor's throat and posting a video of it on social media, in a brutal attack representing a dramatic escalation of communal violence in a country riven by deep religious polarization. The killing comes after months of rising tensions between Hindus and Muslims, and has raised fears it will spark increased violence. [...] In May, a Hindu man in the southern city of Hyderabad was stabbed to death in public by his Muslim wife's relatives. Last year, a Muslim man was beheaded by members of a vigilante group on orders of his girlfriend's Hindu family because they didn't approve of their interfaith marriage. In Rajasthan state in 2017, a Hindu man brutally killed a Muslim laborer and shared a video of the victim being hacked to death and then set on fire.
