The three were returning from a mining site when they were attacked, our correspondent learnt.
A survivor, simply identified as Sunday Samson, said the attackers bore AK 47 rifles, which they used to kill two and used a machete to kill the third one and severe his head.
Confirming the incident, the Plateau State Police, said the Commissioner of Police has since deployed security personnel to the area to beef up security and restore normalcy.
The latest attack came days after the IRIGWE DEVELOPMENT ASSOCIATION, the umbrella body of the IRIGWE nation issued a press statement, calling for vigilance, especially by security agencies, saying attacks such as this were eminent following a release by the Miyyeti Allah Cattle Breeders Association (MACBAN), which had alleged lost of cattle around the area.
The community members who denied the claims had viewed the earlier statement as a move to justify attacks such as the latest one.
The Police spokesman had said the Officer in charge of Homicide had been commissioned to specially investigate the latest claims and prevent any further bloodshed.
Our correspondent can report that late last year, over seventy people were killed from various night attacks in Bassa villages with houses razed and the villagers sacked.
