ABUJA - Suspected Boko Haram militants have kidnapped up to 30 women from nomadic settlements in Nigeria’s northeast, close to where the group abducted more than 200 schoolgirls, residents and Nigerian media said.

Villagers from Chibok, where the schoolgirls were grabbed in April, told Reuters on Tuesday they had met nomads fleeing last week’s raids and saying the kidnappers were demanding cattle in exchange for the women.

“One of them named Mohammed told me Boko Haram held the men at gunpoint and moved from hut to hut taking the women,” said Yahaya Musa. “The abductors told them to bring a ransom of cows,” said farmer Yakub Chibok. Police and army spokesmen said they could not confirm the accounts that women were taken on Thursday in areas outside Chibok.

There were conflicting reports of how many women were abducted from the nomadic settlement near Chibok in Borno state, with one local leader putting the number as high as 40.

But the latest kidnappings, which happened on Saturday in and around the village of Garkin Fulani, eight kilometres (five miles) from Chibok, were the latest in a spate in the area.

The abduction of 276 schoolgirls on April 14 was Boko Haram’s most daring kidnapping in its five-year insurgency. It attracted worldwide attention and prompted an international rescue effort.

“Available information revealed that the gunmen came around noon (1100 GMT) and abducted 20 women and three young men left to keep watch on the village,” said Alhaji Tar, of a local vigilante group.

“All the males in the settlement were away in the bush with their herd (of cattle) for grazing when the abductors came to the village.” There was no immediate indication of where the women were taken and there had been no contact from the kidnappers, but a source at the National Human Rights Commission said no children were seized. The women were aged between 15 and 30, the source added.

Similar kidnappings for ransom have been going on in the area for some time but locals were too afraid to speak out in fear of reprisals from the militants, the official said.

“This is not the first time women are being kidnapped in this area and only released when we pay cattle ransom to the kidnappers. It has happened several times,” said the official.

“They come and go door-to-door bringing women outside and select young women and take them away in their vehicles and demand between 30 and 40 cows for their release”, he explained.

Locals always paid the ransom but do not inform the authorities, he said.

A Borno state government official, speaking on condition of anonymity, said the authorities were aware of the kidnapping of women from the village but denied knowledge of previous abductions.

“This is the first time we are hearing abduction of Fulani women and we are working to establish the circumstances surrounding the kidnap and necessary action to take,” he added.

There was no immediate response from Nigeria’s military or police but Mike Omerri, co-ordinator at the National Information Centre, said they had not received any reports of such kidnappings.

Since the schoolgirls’ kidnap, Boko Haram has intensified its attacks, particularly in Borno, where last week hundreds were feared dead in a militant raid on at least four villages. On Tuesday, police shut three major markets in Abuja, after intelligence that they were the targets for a Boko Haram attack.

A suburban bus station in the capital was hit twice by bombings in April and May, killing nearly 100, while a busy market in the central city of Jos was targeted on May 20, killing at least 118.

Nigeria’s military, which has said it knows where the missing girls are, claimed on Monday that it had prevented “massive” raids on villages in Borno and Adamawa last weekend.

More than 50 militants were killed late on Saturday, while troops seized arms and ammunition, including rocket-propelled grenades and machine guns, as well as vehicles.
