Great!  I can also recommend some websites and articles that might help you understand why some Indian citizens living in India might attack Muslims.  These include articles about discrimination, ethnic tensions, and political unrest.

If you mean "in the past year," I don't think there have been many attacks in India that I've heard about.  If you're asking about violence that people in India are involved in against people in other countries, then that does happen.  Also, if you mean "recently", it's pretty common for Indian citizens to travel to Pakistan and India to visit family members, so that's a very common form of violence, especially because of the historical conflicts between the two countries, but also because of issues of immigration, as you mentioned in your question.  Are you thinking specifically about the time around the end of September, or earlier than that?

Why are Hindu nationalists attacking Muslims?

This seems like a complicated question to me.

Why are people from India attacking Muslims? What's wrong with them?
user
These are two different questions.  I can understand each of them individually.  If you'd like, I can start with the first one, and I can also add a question mark to each statement.  I can also respond “I'm not sure,” or “I don't know.”

I can give you some links to help with that question, and I'm interested in your definition of "people from India" - do you mean Indian citizens?  Indian residents?  People who were born in India and are currently living in India?  Because as you probably know, India has a really large diaspora, including many of its citizens living in other countries, and of course many people from other countries have immigrated to India.  If you want to answer this question, we can discuss what you mean, and I can also recommend some websites that provide information about the history of migration to and from India, as well as about different forms of discrimination.
