Abuja - 61 out of the over 200 Chibok girls abducted in April 2014 have been married to Boko Haram militants
Eight of the school girls have also died during their captivity in the hands of the terroists.
Seven died during air strikes by the Nigerian Air orce while one died due to an unknown cause.
These revelations were contained in a confidential report based prepared for President Muhammadu Buhari and seen by the Thomson Reuters Foundation.
The report was prepared following two weeks of profiling and debriefing of the 21 freed Chibok Girls girls.
The 21 girls were released last month after Nigeria, supported by Switzerland and the International Committee of the Red Cross brokered a deal with the Boko Haram terrorist group.
The freed girls said they were not raped or abused during their stay two years in captivity.
This is contrary to the general perception by human rights groups that most of the girls kidnapped by the Islamist militant group have been used as sex slaves.

According to the secret report, heath workers involved in the screening have confirmed that the girls were not sexually abused while in captivity and that they all tested negative for sexually transmitted diseases.
The girls said the Boko Haram men always assured them that they would eventually go back home to their families and were careful about what they said around the girls and how they treated them.
The report also said the daily routine of the captured girls included personal time in the morning followed by Quranic teaching and cooking meals.
According to the girls, they were not forced into marriage by the terrorists.
