Tunisia: Italy says Lampedusa migrant numbers rising

There has been a sharp increase in the number of African migrants arriving in Italy in overcrowded boats, officials say. More than 3,000 people have reached the small island of Lampedusa - 200km (124 miles) off the Tunisian coast - in the past few days, they report. Arrivals are said to include Somalis and Nigerians as well as North Africans fleeing the violence in Libya.
