Boko Haram pelted women and children with stones as Nigerian soldiers conducted a rescue mission in which more than 10 women were killed.
As gunshots of the military could be heard in the Sambisa Forest in northeast Nigeria, women and girls were stoned to death because they refused to run away with their captors.
One kidnapped woman, Lami Musa, 27, was saved from a forced marriage to one of her husband's killers thanks to the rescue.
Ms Musa, who was pregnant when she was forced to abandon her three children after her husband was killed five months ago, gave birth the night before she was rescued.
As gunfire could be heard, “Boko Haram came and told us they were moving out and that we should run away with them,” the new-mother said. “But we said no.”
Some of the women had to walk to safety, as there were too few vehicles to transport all those rescued.
But three were killed when they strayed into the heavily mined surrounding area, triggering a land mine.
About 10 others were killed when an armoured personnel carrier drove over the bushes they were hiding in. Further women are thought to have died from stray bullets.
Ms Musa and Ms Bulamu are among 275 women and their children who were freed by Nigerian soldiers and are now receiving medical treatment at a refugee camp on the outskirts of Yola, the capital of the north-eastern Adamawa state.
Nigeria's military says it has rescued almost 700 captives of Boko Haram in the past week, suggesting the tide may be turning against the militant group.
It is unknown if any of those rescued are the girls who were taken from a boarding school in Chibok last year, which sparked the “bring back our girls” campaign.
