A Nigerian singer has offered her virginity to terror group Boko Haram in exchange for the 220 schoolgirls the insurgents kidnapped last April.

Adokiye Kyrian, known by many as Adokiye, told Nigerian newspaper Vanguard: "This is 11pm in the night and do you know what I am thinking about?

"Those little girls, where they are and what could be happening to them. It is just unfair. They are too young. I wish I could offer myself in exchange.

"They are between 12- and 15-year-old girls for Christ sake. I am older and more experienced. Even if 10 to 12 men have to take me every night, I don't care. Just release these girls and let them go back to their parents," the 23-year-old singer added.

In April the singer, according to Sowetan newspaper, who is also a UN Ambassador of Peace in Nigeria, offered her virginity to any man who could buy a jet for her mother.

Adokiye is the latest celebrity to join a global campaign demanding the release of the girls.

Prominent political figures and celebrities throughout the world have also taken to social media to demand their return.

Twitter campaigns #BringBackOurDaughters and #BringBackOurGirls attract new supporters, including Hollywood actress Angelina Jolie and US First lady Michelle Obama, every day.

Boko Haram, which is fighting against the Westernisation of Nigeria and wants to establish an Islamic state, abducted the girls in Chibok, Borno State on 14 April.

About 50 of the kidnapped girls managed to escape, but 220 are still missing.

The victims, aged between 16 and 18, are being allegedly smuggled to Cameroon and Chad and sold as brides to militants for 2,000 naira (£7).

Others are being forced to marry their abductors.

Boko Haram is believed to have kidnapped at least 60 more women and girls in Kummabza village, Borno State, this month.

According to Nigeria's former president Olusegun Obasanjo, many of the kidnapped girls will never return home, and only those who get pregnant will have a chance to be released.
