Video - Thousands of Nigerians flee country due to violence

The UN says thousands of people continue to flee the violence in Nigeria, a month since the start of a military offensive in three northern states against the armed group Boko Haram. So far more than 6,000 refugees have arrived in the town of Bosso in neighbouring Niger. Boko Haram, a radical armed group, has been blamed for the deaths of thousands of civilians.
