Our Q&A with director Chris Martin and photojournalist Paul Conroy, hosted by BBC chief international correspondent Lyse Doucet.
On 13 February 2012, two journalists entered war-ravaged Syria. One of them was acclaimed Sunday Times war correspondent, Marie Colvin, known for her fearless journalism. The other was her colleague, photographer Paul Conroy. Their aim was to cover the plight of Syrian civilians trapped in Homs, a city under siege and relentless military attack from the Syrian army. Only one of them returned.
