For foreign countries providing fighters for ISIS, this map is from 2014 but shows that Tunisia is high up on the list:

Inside Tunisia's Extremist Breeding Ground
BEN GUERDANE, TUNISIA—
The outdoor market should be packed, but just a few people have braved a hot sun to haggle over flat-screen TVs and gaudy rugs trucked over from Libya, just 30 kilometers away.
There is also no business at Ben Guerdane’s currency black market; the men manning the dusty sidewalk stalls shoo a visitor away with a surly wave.
One of Tunisia’s poorest towns, Ben Guerdane is largely dependent on cross-border trade — legal and illegal — for its survival. Already struggling businesses faced a fresh blow a few weeks ago, when Libyan authorities temporarily closed the frontier to stop the flow of smuggled oil.
There is an even larger cause for worry. Tunisian authorities have closed their side of the border at least twice since last November to crack down on two other exports: jihadi fighters and weapons. Earlier this year, they completed the first part of a 200-kilometer border fence with Libya to help thwart terrorism.
