Can i claim hra and tax exemption on interest together ?

Hi, 

I have availed a housing loan from April 2013 onwards for an apartment that was under construction and will get possession is in March 2014 i.e. next month (Registration would be done in February last week) . While it's being constructed, I have been staying in a rented accomodation. My question is that - since possession is due within current financial year - can I claim both HRA and Housing Loan Interest for tax exemption for this year?
