Migrant crisis: 'Desperate scenes on Europe's shores'
At least 42 migrants have drowned overnight in two separate shipwrecks in the Aegean Sea, officials say.
The first boat struck rocks near the Greek island of Farmakonisi, while the second overturned near Kalolimnos. Many of those killed were children.
Meanwhile German Chancellor Angela Merkel said human traffickers must not be allowed to profit from exploiting people desperate to reach Europe.
More than a million migrants arrived in Europe illegally last year.
