Nigeria schoolgirls kidnapping: New theory says girls being used as human bombs

A new theory on the missing Nigerian schoolgirls suggests the abducted girls are most likely being used as human bombs.

According to News.com.au, five attacks involving female suicide bombers have been carried out since June 8, with four of them involving teenage girls.

Security analyst Bawa Abdullahi Wase said that the teenage bombers are likely to be the children of Boko Haram

He said their minds have been indoctrinated, just like their parents minds, adding that Boko Haram women have graduated from being helpers who cook and clean to being bombers.

The theory emerges as Boko Haram-linked militants killed nine bus passengers and a soldier in a privately owned vehicle in northern Cameroon on Wednesday.

At least 276 schoolgirls were abducted by the notorious group in April from a secondary school in the north-eastern town of Chibok, triggering international outrage.

The militants are also accused of abducting 10 people, including the wife of the country's deputy prime minister and a local sultan, at the end of July, the report says.
