How a school kidnapping unfolded in Nigeria

The authorities in Nigeria's northern Kaduna state have ordered the closure of all schools vulnerable to attack following the abduction of about 150 students on Monday. Schools located more than a 30-minute drive from a security post will be shut. More than 1,000 students have been abducted since December last year.
