More than 90 refugees drowned in the Mediterranean Sea over the weekend after their overcrowded boat capsized. The refugees had departed from Libya last week as they hoped to reach Europe for safety. Only four people survived. The humanitarian aid group Doctors Without Borders urged for the survivors not to be returned to Libya, where they likely face detention and abuse. Between January and the end of March, some 300 refugees died attempting to cross the Mediterranean, according to the International Organization for Migration.
