Hra and interest on housing loan allowability

Hi,

I have purchased a flat in Kolkata on loan for which I am paying Interest (The amount exceeds 1.5 lakh). I am currently not staying in the flat due to distance and have shifted to a rented apartment in Kolkata itself, paying rent of 16,000 p.m. I recieve HRA from my firm. I am claiming deduction of principal of 1 lakh U/S 80C. I would like to know if I can claim deduction of Housing Loan Interest U/S 24 and HRA U/S 10(13A).

I need to urgently submit my tax planning to my company or they would be deducting tax. Any help would be hugely appreciated.

Thanks
