"What a life I've brought you into. Will you ever forgive me?" That was the harrowing question that Waad al-Kateab asked her newborn daughter in a documentary, "For Sama", which has been shortlisted for an Oscar. The journalist and filmmaker recorded some 500 hours of footage, documenting Aleppo's violent and deadly siege at the hands of the Syrian regime and Russian forces. It's a visual letter about the human cost of the ongoing conflict, and it's dedicated to her daughter Sama. The director spoke to us about her tale of humanity beyond war.
