We've been reporting this week on the latest migrant tragedies in the Mediterranean. Here's what we know. Hundreds are feared dead this week after boats capsized off the coast of Libya. At the same time, more than 10,000 people have been rescued this week alone. And now a grisly story. Italian police say Muslim migrants on a different boat threw 12 Christians off of it. They were also trying to make it to Europe from Libya.
For more on all of this, we turn to NPR's Ofeibea Quist-Arcton. And Ofeibea, first, what can you tell us about this case that Italian police describe as homicide aggravated by religious hatred?
