KADUNA, Nigeria — It was a particularly brutal raid, the kind that had become rare in recent months. Dozens of homes were burned to the ground. Children were abducted and carried off into the bush. People seeking refuge under a familiar tree were blown up by a suicide bomber who had infiltrated their ranks.

The suspected perpetrator is a familiar foe to this part of northeastern Nigeria: Boko Haram, the militant Islamic group that has carried out dozens of attacks across the region in recent years. On Monday, government officials raised the death toll of the weekend rampage to 65 people, with twice that number injured. Residents of Dalori, the site of the latest attack, said the death toll was even higher, with as many as 100 dead.

Boko Haram has marauded across northern Nigeria for years, killing thousands of civilians, burning entire villages and kidnapping hundreds of women and girls — crimes that came long before the group declared allegiance to the Islamic State last year.
