The woman was a 46-year old Italian tourist, the DAEH emergency services said in a statement to local media. It added that three people were taken to medical facilities and six others were treated on site.BBC reported.
Drone footage shows how widespread the fire was, with buildings spanning the Viva Wyndham Dominicus Beach in the town of Bayahibe on fire, and thick black smoke billowing into the air.
The cause of the early-morning blaze is not yet known, but an initial investigation found the flames spread quickly due to wind conditions and the flammable thatched roofs on some buildings.
The country's Emergency Operations Center (COE) said the fire had been brought under control and guests had been moved to other hotels.
