Desperate hands clutched at Ali Elwan’s arms, legs and neck, and screams misted his ears, as he spat out saltwater and fought for three hours to keep afloat in the night, dozens of miles from land. Although a poor swimmer, he lived – one of just 104 survivors from the wreck of a dilapidated old metal fishing boat smuggling up to 750 migrants from North Africa to Europe. “I was so, so lucky,” the 30-year-old Egyptian told The Associated Press in Athens, Greece, where he works odd jobs while he waits to hear the outcome of his asylum application. “I have two babies. Maybe I stay(ed) in this life for them.” Thousands have died in Mediterranean Sea shipwrecks in recent years as migrants from the Middle East, Asia and Africa seek a better life in the affluent European Union. But the sinking of the Adriana a year ago Friday in international waters 75 kilometers (45 miles) off Pylos in southern Greece was one of the worst. Only 82 bodies were recovered, so that hundreds of families still lack even the grim certitude that their relatives are dead. Elwan, a cook whose wife and children are in Cairo, says he still gets phone calls from Egypt from mothers, brothers and wives of the missing. “We (left) home to get best life for family and until now (their families) know nothing about them,” he said. And after a year there are only hazy answers as to why so many lives were lost, what caused the shipwreck and who can be held answerable. Migrant charities and human rights groups have strongly criticized Greece’s handling of the sinking and its aftermath. Human Rights Watch and Amnesty International said Thursday “a credible process for accountability” was needed. “It is unconscionable that one year since this horrific tragedy, the investigation into the potential liability of (Greece´s) Coast Guard has barely progressed,” HRW official Judith Sunderland said in the groups’ joint statement. The Greek coast guard, migration ministry and other officials did not respond to AP requests for comment ahead of the anniversary. Authorities had a coast guard boat on the scene and merchant ships in the vicinity during the trawler’s last hours. They blame smugglers who crammed hundreds of people into an unseaworthy vessel – most in an airless hold designed to store a catch of fish – for a nightmare voyage from Libya to Italy. They also say the Adriana capsized when its passengers – some of whom wanted to press on for Italy after five dreadful days at sea, others to seek safety in Greece – suddenly surged to one side, causing it to lurch and turn turtle. And they insist that offers to take the migrants off the ship were rebuffed by people set on reaching Italy. Elwan – who says he was on deck with a clear view of what happened – and other survivors say the lurching followed a botched coast guard attempt to tow the trawler. He claimed the coast guard hurriedly cut the towline when it became evident the Adriana would sink and drag their boat down with it. “If you find the ship (at the bottom of the sea), you will find this rope” still attached to it, he said.
