(CNN) A mother and her six children were killed early Saturday in a house fire in Clinton, Mississippi, fire officials said.

The children's father made it out of the home after trying to rescue his family, CNN affiliate WJTV reported. He was taken to a hospital with injuries, the station reported.

Officials said the cause of the fire was unknown but investigators were not suspecting foul play.

The father, who suffered smoke inhalation, cuts and burns, initially refused to be taken away by medics out of concern for his family, according to Mark Jones, a city spokesman.

"Once he's capable of being talked to by our investigators, we can get to him," Jones said. "We do know that he was worried and concerned and being cared to by our paramedics and ... at that point he did not want to leave the scene."
