Yemen girl who lost her parents in air strike becomes country's symbol of war

Buthaina Mansur al-Rimi's life has changed drastically since last year -- orphaned in Sanaa, the little girl controversially ended up in Saudi Arabia for medical care and has just returned to Yemen's capital. Her entire immediate family was wiped out in an air strike by a Saudi-led coalition that backs Yemen's government, using an explosive device Amnesty International says was made in the US.
