Greece’s Coast Guard said Wednesday at least three people were confirmed dead and up to 50 remain missing after a boat carrying asylum seekers sank in the Aegean Sea off the coast of Turkey. Rescuers were able to pull 12 survivors out of the water; they were hospitalized with hypothermia. The Missing Migrants Project estimates that, since 2014, more than 23,000 people have died trying to cross the Mediterranean to seek asylum in Europe.
