Islamic terrorist group Boko Haram has killed 11 people and kidnapped at least 20 women as they continue to expand what they call their “caliphate.”

The group says that the predominantly Christian town of Lassa is now under their control.

“As it is now, Boko Haram is fully in charge in Lassa town and has declared the town a caliphate,” one of the escapees from Lassa told Morning Star News. He declined to give his name, saying, “It is no longer safe for us to tell you our names, as doing so may pose a serious threat not only to us but also our relations who are still being held captive by Boko Haram members.”

The terrorists have also declared Chibok and Shani as part of their “caliphate.”

Samuel Dali, president of the EYN in Nigeria, who also has been displaced by the Boko Haram attacks, confirmed the attacks on the three Christian towns, saying many of his church members have been displaced.
