Nigeria talks with Boko Haram but no sign of girls

Nearly a week after Nigeria announced a ceasefire
deal with Boko Haram, which it said would include the release
of more than 200 schoolgirls kidnapped by the Islamist group,
there is still no sign of the girls being freed.
Talks took place this week between the government and the
Islamist militant group in the Chadian capital, but they are
shrouded in secrecy.
