At least 86 people have been killed in fighting between Muslim herders and Christian farmers. The attack is part of a seemingly unstoppable cycle of violence that many consider to be Nigeria's largest security challenge.

Nigerian authorities imposed a dusk-to-dawn curfew in central Plateau state on Tuesday after the deadly fighting, over dwindling fertile land.

Nigeria’s president called for calm after at least 86 people died in clashes between farmers and semi-nomadic herders over the weekend.

State police spokesman Terna Tyopev said, a total of 86 people had died by late Sunday, but  local government earlier estimate about 70.

 

In December 2015, the Nigerian army raided the residence of the leader of the Islamic Movement in Nigeria, Sheikh Ibrahim Zakzaky. Nigerian troops killed over 300 of the cleric’s supporters, including three of his sons.

Despite a court ruling, which ordered his unconditional release in 2016, the government has refused to set him free. Sheikh Zakzaky’s deteriorating health condition has been a matter of serious concern for his supporters.
