(CNN) When Amina Ali Nkeki was kidnapped by the Nigerian terrorist group Boko Haram more than two years ago, she was a mere schoolgirl. 
 
 On Tuesday night, she apparently wandered out of a forest, asking for help, accompanied by a baby and a man who claimed to be her husband, according to witnesses. 
 
 The man is being investigated by Nigeria's joint intelligence center, according to a military statement. 
 
 Amina Ali is the first of the more than 200 Chibok schoolgirls kidnapped by Boko Haram to be freed after the two years in captivity, Nigerian military officials say. 
 
 Military officials and locals gave different accounts of how she was liberated. Nigeria's army said she was rescued by army troops, but a witness told CNN the girl wandered out of the Sambisa Forest in the northeast of the country along with her child and a man. 
 
 The Sambisa Forest, believed to be the terrorist group's stronghold, has long been the suspected location of the girls. As many as 276 of them were kidnapped at gunpoint from their boarding school in Chibok in Borno, northeast Nigeria, on April 14, 2014. 
 
 At least 57 girls were able to escape soon after their abduction, but more than 200 of them remain missing.

 The witness, Aboku Gaji, told CNN he was participating in a nightly patrol on the edge of the Sambisa Forest with the Civilian Joint Task Force, a vigilante group set up to help fight Boko Haram, when the girl and some companions wandered out around 7 p.m. 
 
 He said her name was Amina Ali Nkeki, and he recognized her as one of the missing schoolgirls, although she looked different and was in poor physical condition, as were the baby and man with her. 
 
 "Their bodies didn't look good," Gaji said. "They had had no bath and were in a dirty condition." 
 
 The young woman was part of a group asking for help, including a man who identified himself as her husband and the father of her baby, Gaji said. 
 
 Amina Ali, was found Wednesday with a baby and Mohammed Hayatu, who said he was her husband. 
 
 The man said he had been kidnapped by Boko Haram from the town of Mubi, taken to Sambisa Forest and married to Nkeki. 
 
 Gaji and his commander took the girl to her house, in the settlement of Mbalala, where she was reunited with her mother, Binta Ali, Gaji said. 
 
 Army: We rescued her 
 
 The Nigerian government and army disputed the account, saying she was rescued by government troops that were working with the civilian force. Operations to find the missing girls have intensified recently with a deep push into Sambisa Forest, a military spokesman told CNN's Nima Elbagir.

 "Troops of 25 Brigade Damboa in conjunction with Civilian JTF deployed in one of the blocking positions at Baale, near Damboa rescued one Miss Amina Ali and a suspected Boko Haram terrorist, Mohammed Hayatu, who claimed to be her husband," according to a military statement. 
 
 She was nursing a 4-month-old girl the military said was named Safiya. 
 
 Manasseh Allan, a Chibok youth leader who also confirmed the girl's rescue, said she was brought in clutching the baby she gave birth to in the hands of Boko Haram militants. 
 
 The army said Hayatu is being treated well and in line with the "rules of engagement regarding insurgents who voluntarily surrender to the military." 
 
 Chibok schoolgirl Amina Ali and her baby with Borno State Gov. Kashim Shetima on Wednesday evening. 
 
 After an exam by air force medics the girl and her baby were handed over to the governor of Nigeria's northeastern Borno state, officials said. 
 
 She may be taken to Abuja on Thursday with her parents to meet the President, according to an army statement. 
 
 A distant relative of the Amina Ali, Yakubu Nkeki, said his wife had spoken to the mother of the young woman and confirmed that they had been reunited. 
 
 "It's a joyful time for me," said Nkeki, who is the father of another of the abducted girls. He said the rescued girl would be taken to the state capital, Maiduguri, on Thursday. 
 
 The military confirmed in a statement that "the suspected Boko Haram terrorist and the nursing mother have been taken to Maiduguri for further medical attention and screening." 
 
 'Bring back our girls' 
 
 The girls' kidnapping sparked global outrage, with Michelle Obama, Malala Yousafzai and a slew of other high-profile figures lending their weight to the #BringBackOurGirls campaign.

 But Nigeria's government has proven powerless to recover the girls, most of whom were Christian, and are believed to have been forced by their captors to convert to Islam. 
 
 Last month, CNN obtained a video of some of the missing Chibok girls that had been sent to negotiators by their captors as "proof of life," and showed it to some of the girls' mothers, who had not been shown the footage by officials. 
 
 Boko Haram, based mainly in Nigeria's northern states but responsible also for attacks in neighboring countries, is seeking to implement sharia law. According to a report released in November , the Global Terrorism Index, Boko Haram was the world's deadliest terrorist group in 2014, responsible for 6,644 deaths, an increase of 317% from the previous year. 
 
 Sambisa stronghold 
 
 Two years ago, when CNN first visited Chibok after the mass abduction, parents described how they had followed their daughters' trail to the edge of the Sambisa Forest, which had been overrun by the Islamist insurgents several years earlier. 
 
 But with danger lurking amid the dense vegetation -- an ideal hiding place for the militants and their improvised explosive devices -- the parents were unable to go further. 
 
 Since then, Nigerian soldiers have infiltrated the forest and driven the militants from some of their territory. 
 
 But the group still holds land in the heart of the forest. 
 
 Nkeki Mutah, the vice chairman of the Chibok association of Abuja, told CNN that urgent action was needed to recover the girls. 
 
 "It is now left for the government to act as quickly as possible and we are calling on international leaders to act." ||||| Another schoolgirl kidnapped by Boko Haram in 2014 was released Thursday, two days after Amina Ali Darsha Nkeki was found by vigilante militant group 
 
 A second schoolgirl kidnapped by Boko Haram from the north-eastern Nigerian town of Chibok in 2014 has been freed, according to the Nigerian military. 
 
 An army spokesman said that Serah Luka had been “rescued” on Thursday morning, along with 96 other women and children held captive by Boko Haram. The spokesman, Sani Kukasheka Usman, said that 35 Boko Haram fighters had also been killed in “clearance operations”. 
 
 If the claim is true, she would be the second of the Chibok girls to escape a Boko Haram camp in Sambisa forest in the past two days. 
 
 “She is believed to be the daughter of Pastor Luka,” Usman said in a statement. “During debriefing the girl revealed that she was a student of the [Chibok] school at the time they were abducted. She further added that she hails from Madagali, Adamawa State.” The statement said the girl had only joined the school just over two months before her abduction. 
 
 Luka is currently receiving medical treatment in Borno state where she was found, the spokesman said. 
 
 The first girl to escape, Amina Ali Darsha Nkeki, met President Muhammadu Buhari yesterday. She had been found by members of a vigilante group on Tuesday on the edge of a Boko Haram stronghold after fleeing during an attack on the militants’ camp. 
 
 On Thursday she was flown to Abuja in the presidential jet to meet Buhari. In a press conference at the presidential villa while waiting for the president to arrive, Nkeki first hid her face from the cameras, then greeted Buhari and handed him her four-month-old baby girl, born in captivity. 
 
 The president pledged to continue the search for the remaining Chibok girls who have not been recovered – who number more than 200 – and to fund Nkeki’s education, in a statement released after the meeting. 
 
 
 
 “Like all Nigerians and many others around the world, I am delighted at the news that Amina Ali Nkeki, one of the missing Chibok girls, has regained her freedom,” Buhari said. “But my feelings are tinged with deep sadness at the horrors the young girl has had to go through at such an early stage in her life.” 
 
 He promised Nkeki “the best care” that the Nigerian government could afford. “We will ensure that she gets the best medical, psychological, emotional and whatever other care she requires to make a full recovery and be reintegrated fully into society,” he said. 
 
 “Amina must be enabled to go back to school. No girl in Nigeria should be put through the brutality of forced marriage. Every girl has the right to an education and a life choice.” 
 
 Buhari said that Nkeki offered his government “a unique opportunity for vital information” that could lead to the release of the rest of the Chibok girls, though he said nothing of the estimated 2,000 other women and girls that have been captured by Boko Haram. 
 
 Nkeki’s brother, Inua Ali, who was also at the meeting, confirmed to the Guardian that the president had pledged to look after Nkeki and her family. “We saw and met with the president today,” he said. “He promised to cater for my sister, her daughter and my mother. He promised to put my sister back in school.” 
 
 
 
 In her first two days of freedom, Nkeki has met dozens of Nigerian dignitaries. 
 
 After being briefly allowed home so that her family could identify her, she was airlifted to Maiduguri, the capital of Borno state. She and her baby had medical checks and met trauma specialists before being flown to Abuja. 
 
 Chibok abductions: first girl found, say Nigerian activists Read more 
 
 Nkeki’s age is not known – her brother said she was born in 1995, but according to other reports she was 17 when she was abducted and is now 19. 
 
 
 
 In what commentators called a “desperate bid to claim credit” for the escape of the first of the Chibok girls since the messy aftermath of the 2014 abductions, the Nigerian army on Wednesday said it had rescued a girl it identified as Falmata Mbalala. 
 
 It later admitted that her name was actually Amina Ali and said its troops had rescued her in conjunction with Civilian JTF, the local vigilante force that arms itself with muskets and catapults. 
 
 Abdul Amin Mahmud, a Nigerian commentator and lawyer, criticised the government for attempting to claim credit and for parading her at the press conference. 
 
 “She was roughly handled by the Nigerian army, and she’s a young girl who’s been in captivity for two years,” he said. “The girl is not a trophy. She’s not the elephant man to be paraded at a circus. She has gone through real psychological trauma. She needs care. They transferred her to the governor’s house and to Abuja to meet the president – for what? 
 
 “The issue of the missing Chibok girls has become a political issue. The previous government did nothing, so if the current government can rescue one, it’s seen as a political victory. I worry about the future of these young girls.” 
 
 In contrast to the government’s claims of rescue, Nkeki’s brother said she had been found trying to hide from the vigilantes after running away from the Boko Haram camp. He said she had been brought back to her family home for a tearful reunion with her elderly, widowed mother, Binta Ali. Onlookers said that Ali shouted “Amina! Amina!” when she saw her, and that they nearly fell over as they hugged each other. 
 
 
 
 According to activists, Nkeki said the rest of the Chibok girls were in the forest except for six, apparently killed in the same attack she had tried to escape. It is unclear who launched the attack on the Boko Haram camp; the army did not claim responsibility for it. 
 
 When she was found, Nkeki was with a man who claimed to be her husband, Mohammed Hayatu, whom the army suspect is a Boko Haram fighter. Hayatu was not at the presidential villa but was being investigated, according to Usman. 
 
 “It should be noted that Mohammed Hayatu is well treated in line with Operation Lafiya Dole’s rules of engagement regarding insurgents who voluntarily surrender to the military,” he said. 
 
 
 
 Given Buhari’s claim in December that Boko Haram had “technically” been defeated because it was reduced to suicide missions and controlled no territory, Nkeki’s escape raises questions about the location of her fellow kidnapping victims and the thousands of others taken by Boko Haram. 
 
 Yakub Bulus, the father of another of the Chibok girls, said that the news brought him joy and hope that his daughter would be found. 
 
 “At least one of them has been found now, hopefully she will reveal where the others are, and with God they will all be found. My hope to see my daughter again has been strengthened,” he said. ||||| (CNN) A girl rescued by Nigerian troops from Boko Haram militants does not appear to be one of the girls abducted in 2014 from a school in the town of Chibok, as was initially reported, an activist said Friday. 
 
 Serah Luka, who was rescued Thursday, did attend the school, but wasn't abducted at the same time as the 276 taken from the school on April 14, 2014, according to Bukky Shonibare of the #BringBackOurGirls campaign. 
 
 "However, the same way we rejoice over the return of the Chibok girl, so also is our joy over this one," Shonibare said. 
 
 A Nigerian army officer said Thursday that Luka was part of the mass abduction. On Friday, Army Brig. General Abubakar Rabe declined to address whether Luka was part of that abduction. 
 
 "We shouldn't focus on whether she is one of the Chibok girls or not," Rabe said. "The important thing is that we are pursuing Boko Haram and rescuing human beings on a daily basis. We should be allowed to be concentrate on rescuing other people in our operations." 
 
 The girl was one of 97 women and children were freed during Thursday's operation, according to Col. Sani Usman. At least 35 Boko Haram fighters were killed. 
 
 Serah Luka was taken to a hospital after her rescue. 
 
 Initially Usman said Luka -- the daughter of a pastor -- had started at the boarding school in Chibok a little more than two months before the Boko Haram raid. 
 
 Activists and residents of Chibok disputed the claim and asked for more verification, saying Luka's name was not on the list of those missing. 
 
 Thursday's news came the same day another kidnap victim, Amina Ali Nkeki, met with Nigerian President Muhammadu Buhari at the presidential villa in Abuja on Thursday. 
 
 She had been found two days before in northeastern Nigeria after apparently escaping from the terror group. 
 
 During the emotional meeting, Buhari held the baby Amina gave birth to while a captive of the terror group. 
 
 "Like all Nigerians and many others around the world, I am delighted that Amina Ali is free, but it is tinged with deep sorrow with what she had to go through," Buhari said. 
 
 Amina was accompanied by her family and Borno State Gov. Kashim Shettima, whose residence she had visited the previous night. 
 
 Nigerian President Muhammadu Buhari hold Amina Ali's baby. 
 
 Shettima had treated Amina, who was limping and severely malnourished when she arrived with her baby at his home, like a "VIP guest," a state government official told CNN. 
 
 "She is receiving high-level medical attention and the best doctors in the state are attending to her. The governor ordered for her release from the military as he wanted to make sure she and her baby daughter received urgent medical and psychological attention," he said. 
 
 Separated from 'husband' 
 
 Amina Ali after escaping the clutches of Boko Haram. 
 
 Amina was the first of the so-called Chibok girls to escape since the 276 schoolgirls were kidnapped at gunpoint from their boarding school in northeast Nigeria. 
 
 As many as 57 girls were able to escape almost immediately, but more than 200 have remained missing since then. 
 
 When Amina escaped, she was accompanied by a young man who said he was her husband and the father of her baby. He said he had been kidnapped by Boko Haram and taken to their forest stronghold, where he married Amina. 
 
 But a government official told CNN that Amina had been "completely detached" from the man, who remains in military detention and is being interrogated. 
 
 Bittersweet reunion 
 
 Amina was briefly reunited with her mother on Tuesday night at the family home in Mbalala before being held by the army, CNN learned. 
 
 A neighbor who witnessed the emotional meeting told CNN that her mother, Binta Ali, was very distressed when she first saw her daughter.

 "The mom was very disturbed," said the neighbor, who did not want to be named. 
 
 "She was full of happiness but at the same time seeing the situation of her daughter, who is a Christian, with a baby and a Boko Haram husband and wearing a hijab, she was just crying bitterly," said the neighbor. 
 
 "Even Amina was comforting her mother saying she should be happy to see her alive. She was very happy to see her but she was also very sad."

 Conflicting accounts 
 
 It is still unclear how Amina escaped from the clutches of Boko Haram, but the government official said it was likely as a result of the sustained military campaign in the Sambisa Forest. The dense forest in Nigeria's northeast is believed to be the terrorist group's stronghold, and has long been the suspected location of the missing girls.

 "The governor has ordered that no one should ask her any questions for now but it's likely that she may have taken her chance to escape based on a military attack carried out in the Sambisa Forest," the official said. "I believe more Chibok girls could have escaped and could still be in the Sambisa." 
 
 On Wednesday, a member of a civilian vigilante group set up to help fight Boko Haram told CNN he had been on a nightly patrol on the edge of Sambisa Forest on Tuesday night when when the girl and some companions wandered out around 7 p.m. 
 
 He recognized her as one of the missing schoolgirls, although she looked different and was in poor physical condition, as were the baby and man with her. 
 
 Nigeria's government has said the girl was rescued by government troops that were working with the civilian force. Operations to find the missing girls have intensified recently with a deep push into Sambisa Forest, a military spokesman told CNN's Nima Elbagir. 
 
 Campaign of terror

 But Nigeria's government has so far proven largely powerless to recover the girls.

 Boko Haram, based mainly in Nigeria's northern states but responsible also for attacks in neighboring countries, is seeking to implement sharia law. According to a report released in November, the Global Terrorism Index, Boko Haram was the world's deadliest terrorist group in 2014, responsible for 6,644 deaths, compared with ISIS, which was responsible for 6,073. 
 
 Besides the spate of kidnappings, the group has also pursued a ruthless campaign of bombing marketplaces throughout Nigeria and neighboring countries.
– The families of hundreds of schoolgirls kidnapped by Boko Haram two years ago have been given fresh hope by what the Nigerian military says is another rescue. A military spokesman says that "Miss Serah Luka, who is number 157 on the list of the abducted schoolgirls," was among 97 women and children rescued in a raid that killed at least 35 militants, reports the BBC, although a spokesman for the families of the girls kidnapped in the town of Chibok denies that she is on the list. The military says Luka, a pastor's daughter who joined the Chibok school just two months before the mass kidnapping, is receiving medical treatment, the Guardian reports. On Tuesday, the military announced that it had rescued missing schoolgirl Amina Ali Nkeki from the militants. Since then, she has met with President Muhammadu Buhari and so many other dignitaries that critics are accusing the government of putting a traumatized girl on parade in an effort to score political points. Nkeki was found by vigilantes in the Sambisa Forest after she ran away from a Boko Haram camp with a 4-month-old baby and a man she said was her husband. But while she was meeting the president, the husband was being interrogated as a suspected Boko Haram fighter, CNN reports. Some 217 schoolgirls are still missing, and Nkeki has reportedly said that they are all still in forest camps, apart from six killed in a recent attack.
