At least 12 people were killed and three others abducted when gunmen attacked a mining site in Atoso village in Nigeria's restive Plateau state, a local group leader said on Wednesday.
Dalyop Solomon Mwantiri, who heads the Berom Youth Moulders-Association (BYM), said the attackers, who locals identified as armed Fulani militias, struck late on Tuesday, leaving five others hospitalized with gunshot wounds.
Police spokesperson Alfred Alabo confirmed investigations were underway.
The latest attack underscores persistent insecurity on the Plateau, a flashpoint of Nigeria's volatile Middle Belt region, where ethnic and religious strife has long fueled deadly farmer-herder clashes.
Violence keeps surging despite repeated government vows to restore peace.
Tuesday's attack came just days after four children were killed in a nearby village, Mwantiri said, accusing authorities of ignoring early warning signs.
The BYM is urging the government to deploy more security forces to enforce a ban on open grazing, and rescue the abducted victims.
