Greek shipwreck tragedy sparks protests and calls for action.

Protests have erupted across Greece over the sinking of a boat carrying migrants and refugees that left at least 78 people dead. More than 100 people were rescued from a capsized boat off the coast of Pylos but hopes have faded for hundreds of others who were still missing. A huge search and rescue operation recovered 78 bodies, but authorities estimate the trawler may have carried as many as 750 passengers, who each paid thousands of dollars for passage on the battered vessel.
