Residents in the town of Bosso, which lies next to Malam Fatori but across the border in Niger, said the bombardment began early yesterday and lasted for several hours.
"At around 8:00 am (0700 GMT) we started seeing three military jets encircling Malam Fatori and soon after (they) began dropping bombs," said Idrissa Ari, a Bosso resident.
His account was supported by three others in Bosso but there was no comment from the Nigerian military on the operation.
There was also no initial word on casualties or whether Boko Haram fighters had fled the area.
