Islamic extremists Saturday claimed responsibility for the bombing in Nigeria's capital Abuja that left 75 people dead last Monday. In a video message, Abubakar Shekau, the leader of Boko Haram, taunted authorities and claimed to be living somewhere in the capital.
Meantime, Nigerian officials are still searching for 85 school girls abducted from the northeastern town of Chibok on Monday. Saturday, officials said 44 other girls have escaped from the kidnappers who seized them at a secondary school .
On Friday, school principal Asabe Kwanbura said some of the girls had escaped by jumping from their captor's vehicles while others managed to escape from a camp where they were being held.
The Nigerian military has launched search efforts for the students. Authorities also say vigilante groups and hunters are looking for the girls in the surrounding forest, where insurgents are believed to be hiding.
There have been no claims of responsibility for the attack.
