Suspected Boko Haram gunmen have reportedly kidnapped 20 women from a nomadic settlement in northeast Nigeria near the town of Chibok, where the Islamic militants abducted more than 300 schoolgirls and young women on April 15.

Alhaji Tar, a member of the vigilante groups set up to resist Boko Haram's attacks, says the men arrived at noon Thursday in the Garkin Fulani settlement and forced the women to enter their vehicles at gunpoint. He says they drove away to an unknown location in the remote stretch of Borno state.

Tar says the group also kidnapped three young men who tried to stop the kidnapping.

Boko Haram wants to establish an Islamic state in Nigeria. Some 275 of the kidnapped girls remain missing.
