Sikh labourer Sika was just six months old when he and his elder brother Sadiq Khan were torn apart as Britain split the Indian subcontinent at the end of colonial rule in 1947. Ever since he was a child, Sika yearned to find out about his brother, the only surviving member of his family. 75 years later they have reunited for the first time. During Partition sectarian bloodshed killed possibly more than one million people, families like Sika's were cleaved apart and two independent nations -- Pakistan and India -- were created.
