LAGOS, Nigeria Nigeria's Islamic extremists are claiming responsibility for the massive explosion at a busy bus station that killed at least 75 people in Nigeria's capital, Abuja, this week.
It comes in a new video received Saturday. The leader of the Boko Haram network threatens more attacks saying "We are in your city, but you don't know where we are."
Abubakar Shekau makes no mention of the abductions of more than 100 girls and young women from a remote northeastern school. Officials say dozens of the girls have managed to escape but 85 remain unaccounted for.
Parents and townspeople have joined security forces and vigilantes searching the dangerous Sambisa Forest for the kidnapped girls.
Boko Haram says Western education and influence have corrupted Africans and only Islamic law can save Nigeria.
