Italy has criticised Tunisia for not doing enough to stem the flow of people leaving the country since the overthrow of its previous government.
Frontex, the European Union's border agency, has said it will send officers to prevent the arrival of more migrants, after around 6,000 arrived on the Italian island of Lampedusa earlier this week.
But the Tunisian coastguard says it is already stepping up its own operations.
