Rescuers continue search for capsized boat survivors

A search is under way for 150 migrants missing in the Mediterranean after their boat capsized in rough seas off the Italian isle of Lampedusa.

Italian rescue vessels and a helicopter saved 48 refugees from the boat, which had been carrying about 200 people.

The BBC's Emma Wallis in Rome said that coastguards have not given-up hope of finding more survivors, but conditions were difficult.

The boat was found some 70km (40 miles) from Lampedusa, which has struggled to cope with thousands of migrants from Tunisia this year.
