ABUJA, Nigeria — At least 30 people have been killed in Nigeria’s northeastern Borno region after suspected Boko Haram fighters set ablaze several trucks carrying passengers on Sunday night, eyewitnesses and residents told Reuters.

There was no immediate claim of responsibility, but the Boko Haram group and rival Islamic State in West Africa (ISWA) splinter group have often carried out attacks in the area.

The passengers were stranded on Sunday evening along a military check point due to the curfew imposed by the military in the town of Auno before the attack, resident Bunu Ali who witnessed the attack said.

Auno is about 15 miles from Maiduguri, the state capital. Eyewitness said the insurgents attacked on motorbikes, shooting sporadically. They set at least 18 vehicles ablaze and abducted several people, another eyewitness said.
