Tunisian coast guard retrieves bodies of four migrants

LAMPEDUSA, ITALY - MAY 24: Refugees and migrants are seen swimming and yelling for assitance from crewmembers from the Migrant Offshore Aid Station (MOAS) 'Phoenix' vessel after a wooden boat bound for Italy carrying more than 500 people capsized on May 24, 2017 off Lampedusa, Italy. Numbers of refugees and migrants attempting the dangerous central Mediterranean crossing from Libya to Italy has risen since the same time last year with more than 43,000 people recorded so far in 2017. In an attempt to slow the flow of migrants Italy recently signed a deal with Libya, Chad and Niger outlining a plan to increase border controls and add new reception centers in the African nations, which are key transit points for migrants heading to Italy. MOAS is a Malta based NGO dedicated to providing professional search-and-rescue assistance to refugees and migrants in distress at sea. Since the start of the year MOAS have rescued and assisted 3572 people and are currently patrolling and running rescue operations in international waters off the coast of Libya.
