The perpetrators swept through eight villages, killing people and sending residents to flee, police said with a death toll of 88. Details became known on Saturday.
A spokesman for Kebbi governor Abubakar Bagudu said Sunday the attackers had come from neighboring states of Niger and Zamfara to rustle cattle and destroy crops.
Armed forces have intensified attacks on communities in the region in recent years, forcing thousands to flee into Niger via Nigeria’s northern border. The attackers have become known through mass kidnapping in schools around the world, in which more than 800 students have been kidnapped since December.
The rampant violence triggered a humanitarian crisis, the international aid organization Medecins Sans Frontieres announced on Thursday.
On Sunday, the governor pledged financial aid and “urged communities in the region to be tolerant, accommodating, friendly and peaceful,” his spokesman said in a statement.
