Violence has been reportedly reportedly in areas long-worried by the ISIL affiliates of West Africa (ISWAP) and Boko Haram.

At least 26 people were killed when the truck hit a stationary Northeast explosion in Nigeria.

According to the military and residents, the bombing on Monday killed men, women and children in Borno State near the border with Cameroon. The region has been plagued by armed groups including the Islamic (ISIL) branch of West Africa (ISWAP) and Boko Haram for decades, with violence erupting in recent days.

"26 people died in the explosion, composed of 16 men, 4 women and 6 children," an officer who asked not to be named told AFP.

The Borno State Police did not immediately comment.

International NGO Security Organization provides security to foreign NGOs in northeast Nigeria, said in an internal memo seen by Reuters News that vehicles traveling between the towns of Rann and Gamboru Ngala attacked an IED.

"I attended the funeral of 26 people who died in the explosion; most of them were burned down," Akram Saad, a resident of the nearby town of Rann, told AFP.

A video shows a row of bodies in white plastic bags placed on the morgue floor of Lahn General Hospital.

No one claimed responsibility for the attack. But Abba Amma Muhammad, whose mother was killed, blamed Boko Haram for the incident.

The Boko Haram uprising has plagued northeast Nigeria over the past 15 years, killing more than 40,000 people. The government asserted that despite the ongoing attacks, the groups were largely defeated.

ISWAP is also active in Northern Borno and fired sporadic ambushes on convoys and mines along its highways.

The explosion occurred in recent days of violence in northeast Nigeria, with the death toll rising to at least 50.

Boko Haram killed about 10 "warning" of the Joint Civilian Task Force (CJTF) in Adamawa State, AFP reported earlier on Monday.

The group killed 14 farmers in Borno’s Gvosa district on Thursday, a local official said.

Borno State Governor Babagana Umara Zulum told Nigeria's defense minister and military chief on Friday that Boko Haram and ISWAP were trapped in the Chad Islands, Sambiza Forest and Mandela Mountains on the border with Cameroon due to "military setbacks".
