Rome, Sha'ban 1, 1436, May 19, 2015, SPA -- The wreck of the migrant boat that sank last month, in an incident that is believed to have claimed the lives of about 800 people, will be recovered from the Mediterranean, Italian Prime Minister Matteo Renzi promised Tuesday, according to dpa. Renzi gave an interview to late-night political talk show Porta a Porta that was due to be broadcast later in the day by RAI state television. Extracts of his remarks were published in advance by Italian news agencies. "We will go fetch that boat, the one that sank in last month's carnage, and we will lift it up. I want the whole world to see what happened. It is unacceptable for some people to keep thinking along the lines of 'out of sight, out of mind,'" Renzi said. The UN Refugee Agency, UNHCR, described the April 18 shipwreck as "the deadliest incident in the Mediterranean ... ever recorded." Rescuers found 24 bodies floating at sea, and 28 survivors, who told Italian authorities and aid workers that hundreds more people were aboard the sunken vessel, locked in the hold and unable to escape after it overturned. The Italian navy located the wreck earlier this month, acting on the bidding of prosecutors in Catania who are investigating the accident and have ordered the arrest of two survivors who allegedly steered the vessel. Catania Chief Prosecutor Giovanni Salvi was quoted on the weekend by La Repubblica newspaper as saying that he had no plans to order the recovery of the boat, because it was too expensive and not needed to pursue the criminal case. Salvi's remarks triggered criticism from humanitarian organizations. Renzi said the recovery was expected to cost 15 to 20 million euros (17-22 million dollars), "which I hope the European Union will pay, otherwise Italy will." --SPA 00:00 LOCAL TIME 21:00 GMT www.spa.gov.sa/w
