Malala in Nigeria to meet families of missing girls

The Pakistani schoolgirl and campaigner Malala Yousafzai, who was shot in the head by the Taliban, has travelled to Nigeria to meet the families of more than 200 kidnapped schoolgirls.

They were abducted by the militant Islamist group Boko Haram in April.

Malala is campaigning for better education for all girls.
