Mortage tax deduction interest?

I live in USA. I have a property in India. I pay mortage for it. Every month I pay the EMI in india by transferring to india.
May I claim the interest paid in USA while filing 1040.
I have called IRS and they have asking more questions and they were saying YES. I want to confirm with you all one more time. Please help me even my tax officer is going to read now only.
