Local residents said threats had been posted on social media before the attack.
The curfew, which began at midnight local time, is due to remain in force until 1 April. Residents have been ordered to stay indoors as security personnel intensify patrols and maintain a visible presence across the affected areas.
Security forces were deployed swiftly after the shooting, with troops and other personnel moving to secure the area and restore calm.
Plateau state lies in central Nigeria, where there is often violence between different communities, especially mainly Muslim herders and largely Christian farmers over access to land and water points.
Nigeria faces multiple security challenges across different region – from an Islamist insurgency in the north-east to banditry and kidnappings in the north-west and central areas.
Security watchers say these overlapping pressures have stretched security resources and complicated response efforts.
Sunday’s attack highlights the persistent fragility of local security arrangements and the ease with which violence can disrupt daily life.
While authorities insist the situation is under control, the imposition of a curfew underscores the seriousness of the threat and the urgency of preventing further escalation.
