Venezuelan officials say they're looking into the alleged killing of 28 miners in the southeastern jungle state of Bolivar.

Families say the miners were murdered Friday in a dispute over a gold claim. The South American country's public prosecutor's office said Sunday it was opening an investigation.

State Governor Francisco Rangel is denying that any massacre took place. He says local law enforcement officials found no bodies at the alleged scene of the crime.

A local community is demanding further investigation and has blocked the main road connecting the region to the border with Brazil.

Opposition lawmaker Americo De Grazia says state government may be complicit in the crime. He is comparing the case to the disappearance of 43 Mexican students in the hands of police in 2014.
