Residents of three villages in northern Nigeria have repelled an attack by suspected Boko Haram Islamist fighters, an eyewitness has told the BBC.
About 200 of the militants were killed during the fighting in the Kala-Balge district of Borno state, he said.
The witness said the residents had formed a vigilante group.
The area which came under attack is not far from the site of a market massacre last week in which more than 300 people were killed.
The suspected Boko Haram militants overran the town of Gamboru Ngala 10 days ago on its busy market day in a killing and looting raid which lasted about five hours.
