At least eight people have been found shot dead in rural Ohio, in what have been described as "execution-style" killings.

Pike County's country sheriff says the victims, who were seven adults and one teenager, were killed in four different places not far from each other. Three young children survived the shootings. 

It is still unknown whether those behind the killings are still at large, and police have not identified a motive. But one pastor at the scene was quoted as saying the violence may have been the result of a "domestic situation."
