When three girls showed up Monday at a camp for people who had fled the militant group Boko Haram, they were welcomed and offered a place to sleep.
But early Tuesday morning, as the first light spread across the sprawling camp, two of the girls blew themselves up with bombs they had been concealing, killing 58 people and wounding 78.
The victims were among the more than 50,000 people who had been forced from their homes by Boko Haram’s rampages, only to be confronted with the same horror in the very place they had sought refuge.
The episode at the Dikwa camp for displaced persons follows a pattern of murderous attacks that Boko Haram has carried out since the Nigerian military began rooting the militants from strongholds across the northern part of the country.
Yet Tuesday’s attack could have been worse. One of the would-be bombers recognized her parents and siblings in the camp and decided not to detonate her device, according to Sani Datti of Nigeria’s National Emergency Management Agency. Instead, the girl surrendered to the authorities and warned that future attacks were being planned for the camp, according to other emergency officials.
