This is the story of a baby who was born on a rescue boat, when her Nigerian mother was trying to arrive in Italy five years ago.  This short BBC News video with subtitles (2':47") is suitable for B2 students and it will allow you to listen to a West-African English accent in the voice of the mother.

The vocabulary is not too difficult, you will find words like miracle, a rescue ship, to flee (fled, fled), to struggle [for your life], to bear [a name], to faint, to be in labour, to make it to Europe on a boat, to go through [something], to be in [somebody's] shoes, to be blessed.
