More than 100 people have been kidnapped by gunmen during raids on three villages in northwest Nigeria, a district head and residents said on Saturday.

This is the latest mass abduction of villagers in a region blighted by widespread insecurity.

Kidnapping has become endemic in Nigeria's northwest as roving gangs of armed men abduct people from villages, highways and schools, and demand ransom money from their relatives.

Alhaji Bala, head of a district in the Birnin-Magaji local government area o f Zamfara, said gunmen attacked the villages of Gora, Madomawa and Jambuzu on Friday night. At least 38 men and 67 women and children were missing, he said.

Sporadic gunshots

"But the number of people abducted could be more than that," he added.

Zamfara is a hotspot for kidnapping gangs who carry out attacks and retreat into forests where they have set up camps. The Nigerian military has bombed some of the camps but attacks continue.

Police in Zamfara state have not commented on the latest kidnapping yet.

Aminu Aliyu Asha, the Madomawa village head, said gunmen arrived in his village on motorbikes and shot sporadically before kidnapping several people.

"The abduction breaches the peace agreement between us and bandits. In February this year, we made several ransom payments in order to stop them from attacking our territory," said Asha.

Nusa Sani said his two brothers were among those abducted, while another resident, Garba Kira, added that among the abducted were 15 passengers in a lorry that was passing through the villages.

Mass kidnappings were first carried out by Boko Haram militant group when they seized more than 200 students a decade ago, but the practice has been adopted by armed gangs with no known ideological affiliation. They often demand a ransom to free their captives.
