Migrants killed in 'religious clash'
Italian police say they have arrested 15 Muslim migrants after they allegedly threw 12 Christians overboard following a row on a boat heading to Italy.
The Christian migrants, said to be from Ghana and Nigeria, are all feared dead.
In a separate incident, more than 40 people drowned after another migrant boat sank between Libya and Italy.
Almost 10,000 migrants trying to cross the Mediterranean have been rescued in recent days. Italy has called for more help from the EU to handle the crisis.
