ROME – A major air and sea search and rescue operation is under way south of the Italian island of Lampedusa after a migrant ship capsized.
Italy's ANSA news agency says an estimated 700 people were aboard and only 28 people have been rescued so far.
Barbara Molinario, spokeswoman for the United Nations refugee agency, said Sunday that the Coast Guard operation is continuing. She says the number of victims is not known.
The capsizing comes amid a wave of migrants trying to leave Libya for Italian shores. So far, at least 900 have died trying this year as boats capsized.
