What's the alternate to 1098-E form if the loan is disbursed from a foreign bank?

I came to the US for my Masters. I took an education loan from an Indian bank. After getting a job in US, I started sending money back to the bank towards my education loan. From other posts on this community, I came to know that I can file tax deductions for that education loan. However, my question is what supporting documents would I need for that? Indian banks won't be able to issue a US-recognized form 1098-E. Whats my alternate?
