Abuja - Gunmen in Nigeria killed at least 200 people in multiple raids this week in northwest Zamfara state, a government spokeswoman told AFP on Sunday.

Clashes between herders and farmers over access to land has plagued northwest and central Nigeria for years, with somea groups evolving into criminal gangs known as bandits who kill, loot and kidnap. “This is horrific and tragic. Over 200 persons were buried... due to the invasion by bandits,” a spokeswoman for Sadiya Umar Farouq, minister of humanitarian affairs, said.

“We also worried about the displaced persons who are fleeing in their hundreds from their communities,” the minister added in a statement issued late on Saturday and confirmed by her spokeswoman on Sunday.

More than 10,000 victims have also been rendered homeless after their homes were razed by the bandits while scores are still missing.” On Saturday, four residents had told AFP that gunmen rampaged through Anka and Bukkuyum districts over two days, killing at least 140 people. Babandi Hamidu, a resident of Kurfa Danya village said the militants were shooting “anyone on sight”.

The governor of Zamfara Bello Matawalle has downplayed the death toll, saying only 58 people were killed. “The Emir of Anka gave a list of 22 deaths while the Emir of Bukkuyum gave a list of 36 victims,” said a spokesman for the governor, Zailani Bappa, in a statement late on Saturday.

Nigeria’s President Muhammadu Buhari condemned the attacks, describing them as “an act of desperation by mass murderers.”

The Nigerian government this week officially labelled bandits as terrorists, to bring tougher sanctions against convicted gunmen, their informants and supporters.

                  Military and police operations are currently on in the northwest.

                  Nigeria’s armed forces said they had killed 537 “armed bandits and other criminal elements” in the region and arrested 374 others since May last year, while 452 “kidnapped civilians were rescued”.
