Immigrants part of a group of more than 2.000 people disembarked from Italian military ship "Etna" on July 19, 2014 in the port of Salerno, southern Italy, following Mare Nostrum rescue operations at sea. There has been a sharp rise in migrant landings in recent weeks because of the calm summer weather and growing lawlessness in Libya, with hundreds of migrants now being intercepted by Italian authorities every day. Most of them come from Eritrea, Somalia and Syria but there are also asylum-seekers arriving from Afghanistan, Pakistan and other parts of Asia as well as sub-Saharan Africa.
