Boko Haram fighters killed at least 43 farm workers and injured six in rice fields near the northeastern Nigerian city of Maiduguri on Saturday, an anti-jihadist militia told AFP.

The assailants tied up the agricultural workers and slit their throats in the village of Koshobe, the militia said.

Nigerian President Muhammadu Buhari condemned the attack, saying: "The entire country has been wounded by these senseless killings."

"We have recovered 43 dead bodies, all of them slaughtered, along with six others with serious injuries," said militia leader Babakura Kolo, who helped the survivors. 

"It is no doubt the handiwork of Boko Haram who operate in the area and frequently attack farmers."

The victims were laborers from Sokoto state in northwestern Nigeria, who had traveled to the northeast to find work, said another militiaman Ibrahim Liman who gave the same toll. 

"There were 60 farmers who were contracted to harvest paddy in the rice fields. Forty-three were slaughtered, with six injured," Liman said.

Eight others were missing, presumed to have been kidnapped by the jihadists, he said.

The bodies were taken to Zabarmari village, two kilometers away, where they would be kept ahead of burial on Sunday, said resident Mala Bunu who took part in the search and rescue operation.

In October, Boko Haram militants slaughtered 22 farmers working on their irrigation fields near Maiduguri in two separate incidents.

The violence has also spread into neighboring Niger, Chad and Cameroon, prompting a regional military coalition to fight the militants.
