The fall of Aleppo – one year on

It’s a year since rebels lost the city of Aleppo to Syrian and Russian forces – a turning point in the war, and a decisive win for President Assad. This programme reported extensively from inside the besieged city with reports by filmmaker Waad Al-Khateab – but it was the fate of one man – who became known as the last gardener of Aleppo – that captured the world’s imagination. He was killed when a bomb landed near his garden centre. Tonight we find out what happened to his young son, now 13 – who hasn’t been able to return to the city he once called his home.
