Hundreds of desperate refugees from North Africa drowned this month after their overcrowded boats sank in the Mediterranean. This past weekend there was another close call. More than 700 migrants traveling in five boats were rescued off the coast of Sicily by the Italian navy and coastguard. The European Union’s border agency says about 30,000 migrants have arrived in Italy from Africa during the first nine months of this year. That’s three times higher than the migration for all 12 months of 2012.
