More than 2,000 migrants have died attempting to cross the Mediterranean to to Europe so far this year, following three more shipwrecks that were announced on World Refugee Day. The UN Refugee Agency (UNHCR) said 129 migrants were missing and presumed dead after a their boat, launched from Libya, sank. There were only four survivors. Another boat with at least 85 people, including families with children, broke in half and sank on Monday. Those two wrecks and one other took the death toll over 2,000 for this year; some 83,000 migrants have safely arrived by sea to Europe in 2017.
