Tunisia has dismantled camps housing thousands of undocumented migrants from sub-Saharan Africa, police say.
"It was our duty to end all the disorder," explains a national guard spokesman.
Around 4,000 people of various nationalities left one of the camps cleared by authorities, who say that operations will continue over the coming days.
Tunisia has in recent years become a key departure point in North Africa for migrants making the perilous Mediterranean Sea crossing in hopes of reaching Europe.
