The abduction of the girls sparked global outrage with international pressure piled on the then Goodluck Jonathan-led government to get them back.

With the abduction happening five years ago today, there are a few important things to remember about it, including the names of all those yet to be reunited with their families.
1. Boko Haram kidnapped a total of 276 schoolgirls on the night of April 14, 2014. They were about to sit for their final secondary school leaving examination when they were taken.
The attack on the school commenced late on April 14 and lasted into the early hours of April 15. According to Naomi Adamu, one of the girls that has regained her freedom, the abduction was not planned by the terrorists.
She said they had originally invaded the school to steal its brickmaking machine and not to kidnap the students.
The terrorists reportedly only kidnapped the girls because they had no idea what to do with them after failing to secure the machine, and decided to take them to their leader, Abubakar Shekau.
In a diary she kept with four other girls in their initial days in captivity, Adamu wrote, "They started argument in their midst. So one small boy said that they should burn us all and they said, 'No let us take them with us to Sambisa.'
"Another person said, 'No let's not do that. Let's lead them...to their parent homes.' As they were in argument, then one of them said, 'No, I can't come with empty car and go back with empty car... If we take them to Shekau, he will know what to do.'"
2. While the girls were being transported to Boko Haram's operational base in Sambisa Forest, 57 of them escaped along the way by jumping off the trucks and running into the forest.
Many of them walked through the forest for days before they found their way back home to their relieved parents.
"Some girls started jumping out of the lorry. We said since others are jumping out, it will be better for them to kill us than to take us to an unknown destination. So I and the girls started running," one of the girls recalled.
3. When the new administration of President Muhammadu Buhari was inaugurated in 2015, he opened a channel of communication with Boko Haram and the talks yielded results a year later when the terrorist group agreed to release some of the girls.
21 Chibok girls were released to the government in October 2016, before 82 more girls were released in May 2017.
The government is believed to have paid the sum of €3 million as ransom and released five Boko Haram commanders back to the Islamic sect as part of the deal.
The government has never publicly admitted to paying ransom to the terrorists, but the military has implicitly admitted to the prisoner swap after one of the released terrorists, Shuaibu Moni, featured in a video taunting the Army.
4. Four girls - Amina Ali Nkeki, Maryam Ali Maiyanga, Rakiya Abubakar, and Salomi Pogu - were separately found or escaped between 2016 and 2018.
Nkeki was found by a Civilian Joint Task Force (CJTF) patrol group in May 2016 along with her 4-month-old child, named Safiya, and an alleged Boko Haram member, Mohammed Hayatu, who described himself as her husband.
Troops of the Nigerian Army rescued Maiyanga with her 10-month-old son near Pulka in Gwoza local government area of Borno in November 2016 while Abubakar was rescued with her 6-month-old baby in January 2017.
The last Chibok girl to have escaped till date is Pogu who was found by troops in Gwoza in January 2018 after she escaped.
5. Despite the Federal Government's promises to bring back all the Chibok girls, not much has been heard about the remaining 112 girls.
Their continued stay in captivity has given rise to many theories about their fate with some of them reported, several times, to have died as far back as 2014. Many others are reported to have married their captors and opted to remain with them.
Kabu Yakubu, father to Dorcas Yakubu who's still with the terrorists, told Pulse that he still hopes for his daughter's safe return.
"We're pleading with the government up till this time to rescue those who are still alive," he said.
The Bring Back Our Girls (BBOG) group that was created to advocate for the return of the girls continues to call on the government to show commitment towards securing their freedom.
"As a movement, we hold on to hope that the Chibok girls will return because we do not have any reason to do otherwise as long as they remain alive," BBOG spokesperson, Nifemi Onifade, told Pulse on Saturday, April 13.
