Greek Coast Guard Under Scrutiny After Deadly Migrant Shipwreck

The Greek coast guard has defended its response to a shipwreck off the country's south coast that left more than 500 migrants presumed drowned, as criticism mounted over the years-long failure to hammer out a comprehensive policy on migration into Europe. Patrol boats and a helicopter spent a third day scouring the area of the Mediterranean Sea where the packed fishing vessel capsized early Wednesday, in what the U.N. migration agency said could be the second deadliest shipwreck recorded.
