Muslim herdsmen from the Hausa and Fulani tribes are being blamed for numerous attacks on villages in the northern state of Kaduna.
Having recently returned from Kaduna, Atta Barkindo, a PhD student at the School of Oriental and African Studies in London, told World Watch Monitor: "Christians are really very angry.
"On social media, some groups are thinking of taking revenge, while others are calling for the creation of a southern Kaduna State, defected from the predominantly Hausa-Muslim regions of Kaduna State."
Heavily-armed Fulani herdsmen targeted the Christian settlements of Kagoro and Kafancha between 7th and 12th January, leaving countless bodies behind.
Islamic extremists are also thought to be behind the killing of 45 people at the hands of gunmen in the village of Chaiwai (pictured), last November.
World Watch Monitor, a Christian organisation reporting on Christians under pressure for their faith, said: "The situation in southern Kaduna has become so bad that the UN Special Rapporteur on Extrajudicial, Summary or Arbitrary Executions is investigating the killings."
The Kaduna government claims foreigners motivated by past attacks against them are to blame for the recent attacks on Christian communities in the state, while the national government says it believes the incidents are not religiously-motivated.
The Christian Association of Nigeria, however, believes the attacks are religiously motivated and form part of a bid by Islamists to wipe out Christianity in southern Kaduna.
According to the Catholic Diocese of Kafanchan, 808 people have been killed in 53 villages across four parts of southern Kaduna between April and Dec 2016.
