Malala Yousafzai, the teenage Pakistani schoolgirl who was shot in the head by the Taliban for campaigning for girls' education, met on Sunday with the relatives of the Nigerian schoolgirls kidnapped by Boko Haram.
She pledged to help free the girls abducted by the Islamist militants.
Malala, 16, met with parents of the more than 200 girls who were kidnapped from a school in the northeastern village of Chibok in April.
Boko Haram, a Taliban-inspired movement, say they are fighting to establish an Islamic state in religiously mixed Nigeria.
The group, whose name means “Western education is sinful," has killed thousands and abducted hundreds since launching an uprising in 2009.
Some of the parents broke down into tears as Malala spoke at a hotel in the capital Abuja on Sunday.
“I can see those girls as my sisters ... and I'm going to speak up for them until they are released,” said Malala, who celebrates her 17th birthday on Monday in Nigeria, where she is scheduled to meet with President Goodluck Jonathan.
“I'm going to participate actively in the 'bring back our girls' campaign to make sure that they return safely and they continue their education.”
The girls' abduction drew unprecedented international attention to the war in Nigeria's northeast and the growing security risk that Boko Haram poses to Nigeria, Africa's leading energy producer.
A #BringBackOurGirls Twitter campaign supported by Michelle Obama and Angelina Jolie heaped pressure on authorities to act, and Jonathan pledged to save the girls, drawing promises of Western help to do so.
But several weeks on the hostages have not yet been freed and media interest has waned.
Bomb plot uncovered
In addition, Boko Haram, now considered as the main security threat to Nigeria, is growing bolder.
Police said on Saturday they uncovered a plot to bomb the Abuja transport network using suicide bombers and devices concealed in luggage at major bus stations.
“I can feel ... the circumstances under which you are suffering,” she said. “It's quite difficult for a parent to know that their daughter is in great danger. My birthday wish this year is.. bring back our girls now and alive.”
Taliban militants shot Malala for her outspoken views on women's right to education.
She survived after being airlifted to Britain for treatment and has since become a symbol of defiance against militants operating in the tribal areas along the Pakistan-Afghanistan border.
She has won the European Union's prestigious human rights award and was one of the favorites to win the Nobel Peace Prize last year, although the award ended up going to the Organization for the Prohibition of Chemical Weapons.
