A faction of Boko Haram, the Islamic State West Africa Province (ISWAP), has threateed to keep Leah Sharibu as a slave.

Africa News 24 reports that she is the only Christian among the 110 girls abducted at the Government Girls’ Science and Technical College, Dapchi, Yobe state, on February 19, 2018.

The terrorists made this vow after kiling Hauwa Liman after a deadline they gave to the Federal Government to meet their demands expired.

While other girls were released, Leah was kept back because she refused to renounce her Christian faith.

There has been a global plea for her release.

The group said in the statement that Alice Ngaddah, a Christian who works with UNICEF, will also be kept as a slave.

“From today”, ISWAP said, Sharibu, 15, and Ngaddah, a mother of two, “are now our slaves”.

“Based on our doctrines, it is now lawful for us to do whatever we want to do with them,” the group further said.
