New Delhi has seen the worst sectarian violence in decades after Hindus and minority Muslims clashed — along with security forces attempting to put down the violence —over the controversial new citizenship law, which prioritizes citizenship for non-Muslims from neighboring countries who immigrate.

"This was the first time that the protests have set off major bloodshed between Hindus and Muslims," crossing "an old and dangerous fault line," The New York Times reports.

Shortly before concluding his two day visit Trump was asked about the unrest by reporters. He said he "heard about" the law but that it is "up to India" to handle.

"As Air Force One flew Trump and his delegation out of New Delhi late Tuesday, Muslim families huddled in a mosque in the city's northeast, praying that Hindu mobs wouldn't burn it down," The Associated Press reports.
