Cops alerted before Jos blast, Nigerians says

Jos - A trader from the market in Nigeria's central city of Jos where two explosions left more than 130 people dead last week says police failed to act after traders alerted them about an abandoned car hours before the blasts.

Kabiru Muhammad Idris, a member of the trader's welfare committee at the Terminus market, says police only removed the plate number from a bus after the warning. Other witnesses confirmed his testimony.

Amnesty International said the authorities also failed to act despite warnings hours before Boko Haram militants kidnapped more than 300 schoolgirls from the remote town of Chibok in April.
