Bombs planted on a roadside in northeastern Nigeria detonated, killing at least 26 people in several vehicles, including women and children, police said Tuesday.
A Daesh terrorist group affiliate in the West African country claimed responsibility for the Monday attack.
The blasts happened on a busy road connecting the towns of Rann and Gamboru in Borno state, near the border with Cameroon, Nigerian police spokesperson Nahum Daso told The Associated Press.
Multiple explosives planted along the route ripped into several civilian commercial vehicles coming from Rann, killing at least 26 people, he said.
Most of those killed were local farmers and traders crowded in a Toyota pick up van that drove over a land mine, Daso said. He said the mine was buried by suspected militants from the Daesh affiliate known as IS West Africa Province.
Besides the dead, at least three people were injured and were taken to nearby medical facilities for treatment. Security forces have since secured the area and begun clearance operations.
Abba Modu, a member of the Civilian Joint Task Force, a vigilante group that supports the military in the fight against Daesh terrorists, said the explosives may have been intended for security operatives who regularly patrol the highway.
"Terrorists often plant IEDs in craters or under sand on severely damaged sections of roads, typically targeting soldiers," Modu said.
The Islamic State West Africa Province, also known as ISWAP, claimed responsibility for the attack in a statement on Telegram on Tuesday.
The Daesh-linked group is an offshoot of Boko Haram, Nigeria's homegrown terrorists who took up arms in 2009.
In 2016, ISWAP broke away from Boko Haram following a dispute over leadership and the strategy of attacking civilian targets such as mosques and marketplaces.
The conflict between Nigeria and Daesh terrorists is Africa's longest struggle with militancy. It has spilled into Nigeria's northern neighbors Chad, Niger and Cameroon, and has left some 35,000 civilians dead and more than 2 million displaced, according to the U.N.
Nigeria's northeastern region has been particularly hard hit by Daesh violence.
Earlier this month, a roadside bomb suspected to have been planted by Daesh terrorists in northeastern Nigeria struck a passenger bus and killed eight people.
On Tuesday, the Nigerian military appointed a new commander, Maj. Gen. Abdulsalam Abubakar, in the fight against Boko Haram and the Islamic State West Africa Province insurgencies in the northeast, the spokesperson for the operation said in a statement.
