Officials say 86 people died in the latest attack in the northeastern Nigerian city of Maiduguri on Saturday.
The militants opened fire on residents, set fire to houses and targeted a crowd with suicide bombers, according to security and medical officials. A survivor hidden in a tree says he watched Boko Haram militants firebomb huts and heard the screams of children burning to death.
A Nigerian military spokesman, Colonel Mustapha Ankas, said Boko Haram militants launched an attack on the Dalori community, nearly 5 km east of Maiduguri in Borno state.
"While people were running for their dear lives...three female suicide bombers attempted to make their way into the crowd...and subsequently got blown up," he said, but didn’t give a figure for the number of casualties.
It was the third and most deadly attack this week suspected to have been conducted by the militant group, which has stepped up its hit-and-run attacks on villages as well as suicide bombings on places of worship or markets since it started losing control of territory.
An official of the state emergency agency who was at the scene said there were 12 bodies there burnt beyond recognition.
"We can't even pick those ones, they were seriously burnt," the official said, speaking on condition of anonymity.
In neighbouring Adamawa State, a suicide bomber believed to be from Boko Haram killed about 10 people on Friday after at least 12 were killed on Wednesday in an attack on the Borno State village of Chibok, from where over 200 schoolgirls were abducted in 2014.
Separately, twin suicide attacks by suspected Boko Haram militants killed at least three people in two locations near Lake Chad, around 100 km (60 miles) north of the Chadian capital N'Djamena, security sources said.
Boko Haram was formed in 2009, and has killed thousands of innocent civilians through the years in numerous African countries. The militant group swore allegiance to DAESH in 2014.
In the past six years some 17,000 people have been killed by the militant group, which also has caused around 2.5 million people to flee the area.
Maiduguri's population has doubled in size over the last few years to around 4 million as it has become the refuge for most of the displaced nearby population.
