Relations with Italy have been strained by a flood of migrants from Tunisia to Italy since the start of the political unrest. Over 23,000 migrants, most of them Tunisian but many from Libya and Sub-Saharan Africa, are estimated to have entered Italy from Tunisia between mid-December 2010 and end-March 2011, as a result of the breakdown in the Tunisian police and security services that had previously patrolled the coast. Some 18,000 migrants arrived at Lampedusa, a small Italian island with a population of only 5,000, in the first three months of 2011, compared with just 27 in the same period of 2010. Hundreds of migrants are feared to have drowned as unseaworthy boats capsized. The Italian government has criticised the Tunisian authorities for not doing enough to stem the flow of migrants. The Italian prime minister, Silvio Berlusconi, facing political pressure from anti-immigrant political parties in Italy, travelled to Tunis in early April for talks with the Tunisian authorities. Mr Berlusconi said that Italy would help to finance and equip Tunisian anti-immigration activities; the Tunisian government had agreed that an Italian technical team would stay in Tunisia to work with local officials and that the Italian navy would help to patrol the Tunisian coast. Mr Berlusconi could not, however, get Tunisia to agree to the mass repatriation of the 23,000 migrants who will now be given six-month visas, which will probably allow most of them to travel to other EU countries, such as France and Spain, where many have relatives. However, the Tunisian government agreed that new migrants would be repatriated. Italy provided Tunisia with EUR80m (US$59m) of aid and equipment and a EUR150m credit line at the end of March, and promised a further EUR350m at the start of April.
