Refugees from war or economic migrants?

There's one passage in this Breitbart report http://www.breitbart.com/london/2017/07/13/four-thousand-african-migrants-picked-up-off-libyan-coast-shuttled-to-italy/ on immigration from Africa into Italy that caught my eye :

'Based on statements received at the time of landing in Italy, the 2017 migrants home countries are Nigeria (14,504), Bangladesh (8,268), Guinea (7,844), Ivory Coast (7,455), Gambia (5,022), Senegal (4,914), Mali (4,862), Eritrea (4,553), Morocco (4,190) and Sudan (4,051).'

The African countries are not all war torn but what's that country from where the second highest number of immigrants came? Bangladesh? Poor yes, but not war torn.

Somehow I doubt that the institutionally pro unlimited immigration BBC will choose to report such inconvenient numbers, that might let the cat out of the bag.
