Obamas 'heartbroken' over kidnap on Nigeria girls
US First Lady Michelle Obama has said the mass kidnap of Nigerian schoolgirls is part of a wider pattern of threats and intimidation facing girls around the world who pursue an education.
She said she and her husband Barack Obama were "outraged and heartbroken" over the abductions, which the Islamist militant group Boko Haram has claimed responsibility for.
