For six months the world has waited for news of the fate of more than 200 girls abducted by Nigerian militant group Boko Haram.As the Nigerian government insists a deal to release the "Chibok girls" is being negotiated, three girls who escaped their captors have told their story to BBC Hausa.
Lami, Maria and Hajara were at school in Chibok, north-eastern Nigeria, when they were kidnapped in April. Best friends Lami and Maria escaped by jumping from the back of a truck. Hajara was taken to a camp but later fled with another girl.
To protect the girls' identity we have portrayed their story as an animation, and provided an edited transcript of their account below.
The girls' names have been changed for their protection.
Lami: It was Monday night. We had exams the following day. Then we started to hear shootings in the town. So we went out. We phoned our parents to tell them what was happening in the town. They told us to run away when we got the chance. We told them that the town was already surrounded so there was no way we could run.
Maria: Lami woke me up saying: "Maria didn't you hear what's happening? Haven't you heard sounds of shooting from the town?"
I said we should climb the wall and run away. She said: "No. No-one has run away. We should gather in one place and wait to see what's going to happen."
Other girls said nothing would happen to us. "We're girls. They don't do anything to girls. We should wait and see what God would do."
Lami: We were at the school when suddenly three Boko Haram members entered.
They said: "If any of you attempt to leave we'll kill all of you." When we went out they were everywhere. They gathered us where we have our school assembly. As we were there they kept burning the school. They burnt everything.
Hajara: They asked us to get out of the gate, saying that when we were out they would let us go back to our homes. They said whoever did not have a headscarf or shoes should go and get them. They then asked us to climb on to a lorry, on top of the food loaded in it. The lorry was so high that we couldn't easily climb on.
Maria: They said to us: "You're only coming to school for prostitution. Boko (Western education) is haram (forbidden) so what are you doing in school?"
We kept quiet. I think there could have been about 100 Boko Haram members - they were all over the school. They outnumbered us. They took us away in their vehicles. We were sitting on oil drums in the vehicle. Our vehicle was really overloaded. We were saying to one another that we should throw away our shoes and scarves so that if our parents came they would know the road we had taken.
Hajara: The vehicle became full before I could get on. There were about 100 of us walking. We stopped at one town and people brought us water. I saw one of those who brought us water changed his clothes and joined the Boko Haram men. They then put us in other vehicles.
They put the rest in the boots of cars. Some of the Boko Haram members were so small that if I were to grab their necks I could break them. Some couldn't even carry their guns properly.
Maria: We were wondering where we were being taken to. When we entered the vehicle, Lami said to me: "Shouldn't we jump out of the vehicle here so that we may possibly escape? There are no other vehicles close by."
Hajara: I thought, it's preferable to have these people shoot me as I run than have them humiliate me. They kept saying to us: "Make sure you put on your scarves. Make sure you put on your scarves. We'll shoot any girl we see without a scarf. And any girl who jumps out will die."
I was about to jump out when one girl held me back and said they'd shoot me if I did.
"What's the difference," I said. "Is it not to the same death we're going? They should shoot me here and let my corpse be collected."
I was crying and praying until we reached the camp.
