It's been 16 days since scores of girls and young women were kidnapped from the Chibok Girls Secondary School in Nigeria. About 220 remain missing, the AP says the school's principal estimates.

On Wednesday, hundreds of their mothers and countrywomen marched to the National Assembly in the capital, Abuja, to protest a lack of action, the Associated Press reports. A similar march was held in Kano, in the country's north.

“The leaders of both houses said they will do all in their power, but we are saying two weeks already have passed, we want action now,” activist Mercy Asu Abang told the AP.

“We want our girls to come home alive — not in body bags,” she said.

Blame for the kidnapping has been placed on the terror group Boko Haram. A community leader for Borno state, where Chibok is, said the group is demanding a ransom for the students' release, the AP says. That comes as other stories are told of the girls' fate: The Guardian reports that some relatives have been told that the girls have been married off, and the BBC reports that some of them have been taken to neighboring countries.

And so the women marched, carrying signs that demanded, "Find our daughters."
