( CNN ) -- The nonprofit that pushed last month for Venezuelan officials to investigate reports of a massacre in an Amazon indigenous community said Monday that it now believes there was no attack there . `` Having received its own testimony from confidential sources , Survival now believes there was no attack by miners on the Yanomami community of Irotatheri , '' said Stephen Corry , director of Survival International . The statement comes after Venezuelan state media over the weekend published several reports detailing officials ' accounts from the area , also concluding that no massacre had occurred . Venezuelan officials : Reports of indigenous massacre false . An aerial flyover and ground operation to the community in a remote region along the Brazil-Venezuela border showed no signs of an attack , Venezuelan Brig . Gen. Jesus Zambrano told state-run VTV . `` We can testify that nothing happened , '' he said . Investigators `` also visited other communities in the region , before reaching Irotatheri , and also nothing happened there . '' On Saturday , Venezuela 's government ombudswoman said the report was fueled by second-hand hearsay . `` It was a false , biased report , '' Gabriela Ramirez told reporters . `` The report was made by an indigenous person that heard that another organization had said it . '' Last month allegations of the reported massacre trickled out of the area , where unauthorized Brazilian gold miners have long clashed with indigenous groups . A declaration on the Survival International website last month said members of a neighboring indigenous community had heard reports of a massacre from Irotatheri 's residents . The declaration , purportedly from a group of organizations representing indigenous people and communities in the Amazon , said of about 80 Yanomami people who lived in the Irotatheri community , only three survivors had reportedly been found . Survival International , which advocates tribal peoples ' rights worldwide , had described it as an `` atrocity . '' In his Monday statement saying that Survival no longer believes there was an attack , Corry said visitors to the area `` had heard stories of a killing in July . '' `` We currently do not know whether or not these stories were sparked by a violent incident , which is the most likely explanation , but tension remains high in the area , '' he said . Venezuelan officials said last Wednesday that they were investigating the reports of an attack . Several days later , a top official said visits to the region revealed that reports about the alleged massacre were false . On Saturday , a report from Venezuela 's AVN news agency said investigators from Venezuela 's air force concluded that `` levels of illegal mining in the area were minimal . '' On Monday , Corry disputed that claim , saying `` many illegal gold miners are currently operating '' in the area . `` The Venezuelan government 's reaction remains shameful . It has not said , even now , that it will remove the miners , and it immediately denied having found 'evidence ' of killings , before even concluding its own investigation , '' Corry said .
Survival International `` now believes there was no attack '' Last month , it urged officials to investigate reports of a massacre . Venezuelan officials also say there is no evidence that a massacre occurred . Hearsay fueled a `` false report , '' an official says .
