Escaping from Boko Haram - the people who fled Baga

Eyewitnesses in Nigeria have been describing the destruction and loss of life in the north-eastern region during attacks by the militants of Boko Haram.

Hundreds of people have been killed in the past few weeks and during the past 18 months the attacks are thought to have claimed more than 5,000 civilian lives.

Some 750,000 people have been forced from their homes.

One of the worst attacks was in the remote town of Baga two weeks ago.

The BBC's Thomas Fessy has tracked down some of those who managed to flee.
