One Year Later: Nigerian School Girls Still Missing

Tuesday marks one year since 276 schoolgirls were kidnapped by Boko Haram Islamists in Nigeria.

The girls were taken from a school in the northeastern village of Chibok. Fifty-seven of the girls escaped, but the others have never been heard from.

Abubakar Shekau, leader of the terror group, said all of them were converted to Islam and "married off."

The widely publicized kidnapping sparked an international campaign for their safe return called, #BringBackOur Girls.

On the one-year anniversary of the abduction, Nigerian President-elect Muhammadu Buhari said he cannot promise that authorities will find the missing girls.

"We do not know if the Chibok girls can be rescued. Their whereabouts remain unknown. As much as I wish to, I cannot promise that we can find them," Buhari said in a statement.

CBN News Sr. International Correspondent George Thomas, who has reported extensively on Nigeria, spoke more about the realities on the ground surrounding this grim anniversary. Click play to watch more.

Meanwhile, activists met in Nigeria's capital for a vigil to commemorate the tragedy. They wore red tape over their mouths, symbolizing the stolen voice of the school girls.

"We should have protected them, we failed them, each and everyone of us we failed them, and the next best thing we should have done is to have rescued them and up till now we have not done that," activist Aisha Yesufu said. "And that's a shame for this country and the world at large."

Boko Haram has kidnapped more than 2,000 women since early 2014.
