Government response to Nigeria kidnaps ‘unacceptable’

Protesters in London have voiced their anger at the Nigerian government's response to the abduction of more than 200 school girls.

One woman said the government was "just sitting there, doing nothing. It's totally unacceptable."

She said the country's first lady should be "doing something about it", as a mother herself.

A man who was with her told the BBC's Ben Geoghegan the system was broken.
