“Two-hundred and sixty-seven personnel from various public institutions and organisations responded to the fire and the response is ongoing,” he wrote on X.
Speaking to Turkish news outlet TRT, Bolu Governor Abdulaziz Aydin said the fire began on the fourth floor of the 11-storey hotel at about 3:30am (00:30 GMT). Hours later, firefighters were still working to put it out.
The cause of the fire will be investigated by authorities, he added, noting that it broke out on the restaurant floor.
Two of the victims died after jumping out of the building in a panic, Aydin told the state-run Anadolu news agency. There were 234 guests staying at the hotel, he said.
