ROME, Muharram 25, 1438, October 26, 2016, SPA -- Aid group Doctors Without Borders (MSF) said on Wednesday 25 migrant men and women were found dead at the bottom of a rubber boat in the Mediterranean, and 107 survivors were rescued from the same raft, according to Reuters. The bodies were discovered late on Tuesday, an MSF spokeswoman said. MSF's Mediterranean rescue unit said on Twitter: "23 of the rescued people had horrific chemical burns, 7 were so severely injured that they needed to be evacuated to Italy, 2 by helicopter". More than 3,500 people have died or disappeared trying to cross the Mediterranean from North Africa this year, the International Organization for Migration estimates. Rescuers plucked 500 migrants from overcrowded boats to safety on Tuesday, Italy's coast guard said. --SPA 17:46 LOCAL TIME 14:46 GMT www.spa.gov.sa/w
