The protests are in opposition to attacks that have taken place over grazing rights on land in the region.
The nomadic Fulani gunmen, accused of attacking villages, have been accused of praying on remote villages that are far from army bases and do not have the means to fight back.
Protest organiser Dr Daniel Meshak said four young people had been ambushed and killed at Kura Falls in Barkin Ladi Council while travelling to Jos to take part in the protest.
He has called on Nigeria's Federal Government to "prioritize the security situation on the Plateau" and "resettle, rehabilitate and compensate the victims of the attacks in a similar fashion it plans for victims of terror attacks in the North East."
Marches also took place outside Government House.
Andy Dipper, Chief Operating Officer of Christian Solidarity Worldwide, said, "The violence committed by Fulani gunmen must be addressed in tandem with that of Boko Haram, especially given indications of a possible link between the two groups in Plateau State with the reported discovery of a training camp in Riyom LGA last year.
"In addition, victims must receive compensation and be given every assistance to rebuild their lives.
"The seeming impunity with which these gunmen continue to murder villagers fuels retributive violence and contributes to a dangerous surge in lawlessness.
"To offset the continuing deterioration in rule of law, we call once again for the formulation of a holistic security strategy that encompasses every crisis-affected state, that addresses both sources of violence and secures justice for all victims as a matter of urgency."
Anglican Archbishop of Jos, Rt. Rev Dr Benjamin Kwashi said it was "sad to note that most victims of the attacks are harmless children, some infants, women and youth."
The Archbishop has appealed to the President of Nigeria for effective intervention to end the killings, adding that "attention should not be concentrated only at the north east alone; people are being killed here in Plateau, Benue, Nasarawa and Kaduna."
These coincided with the visit of United Nations Secretary General Ban Ki Moon, who was given a petition detailing the plight of the targeted communities.
Religious leaders, politicians and NGO's attending - including the Bring Back Our Girls campaign.
Since President Buhari took to power in May, around 500 people have died in attacks attributed to Fulani gunmen.
