Marie Colvin: 'A career defined by her humanity'

Tributes have been paid to Marie Colvin, the highly respected Sunday Times reporter, following her death in the Syrian city of Homs.

The BBC's Fergal Keane looks back at her career, one he says was "defined by her humanity".

Remi Ochlik, an award-winning French photographer, and several other people were also killed when shells hit a makeshift media centre in the Baba Amr district.
