The UN Office for the Coordination of Humanitarian Affairs in Nigeria (OCHA) said no fewer than 110 Nigerians were slaughtered by Boko Haram on Saturday.
Edward Kallon, the UN humanitarian coordinator in the country described the attack the deadliest attack on civilians this year.
“I am outraged and horrified by the gruesome attack against civilians carried out by non-state armed groups in villages near Borno State capital Maiduguri,” Kallon said in a statement.
“At least 110 civilians were ruthlessly killed and many others were wounded in this attack,” he added.
Initial tolls indicated 43 killed in the massacre.
Kallon, citing “reports that several women may have been kidnapped”, called for their immediate release.
Some locals blamed the attack on Boko Haram fighters, but Bulama Bukarti, an analyst with the Tony Blair Institute, said rival group the IS-affiliated Islamic State West Africa Province (ISWAP) were more active in the area.
“ISWAP is the likely culprit,” he tweeted.
Kallon, in his statement, said: “The incident is the most violent direct attack against innocent civilians this year.
“I call for the perpetrators of this heinous and senseless act to be brought to justice,” he added.
The violence centred on the village of Koshobe near the Borno state capital Maiduguri, with assailants targeting farm workers harvesting rice fields.
One pro-government anti-jihadist militia said the assailants tied up the labourers and slit their throats.
Kallon said the assailants — “armed men on motorcycles” — also targeted other communities in the area.
“Rural communities in Borno State are facing untold hardships,” he added, calling for more to be done to protect them and to head off what he said was a looming food crisis there.
Borno Governor Babaganan Umara Zulum attended the burial Sunday in the nearby village of Zabarmari of 43 bodies recovered on Saturday, saying the toll could rise after search operations resumed.
The victims included dozens of labourers from Sokoto state in north-western Nigeria, roughly 1,000 kilometres (600 miles) away, who had travelled to the northeast to find work, it said.
Six were wounded in the attack and eight remained missing as of Saturday. – AFP.
