Activists rallied in the Nigerian City of Lagos this week to call on the government to work harder to bring back the so-called “Chibok Girls” abducted by terrorists three years ago.

Boko Haram terrorists stormed a secondary school in the remote town of Chibok in northeast Nigeria and abducted 276 girls three years ago this week. While the terrorist group has released some of them, 195 remain unaccounted for.

“We don't want any more excuses. Mr. President promised two years ago. Now what has changed since then?” said Ayo Obe, a member of the advocacy group BringBackOurGirls.

Some of the girls were released last October. But since then, despite initial optimism that Boko Haram would release more of the girls, nothing has happened yet.

“The Nigerian military has been making effort. The current administration has been making tremendous efforts and commitment towards the rescue of the girls. We want to encourage them to do more,” said Hadiza Bala, co-convener of the group. "We believe that our military will be able to rescue these girls and we are prayerful that within the shortest period, these girls will be rescued.”
