Hasan Dabla has been fishing in the Arabian Sea for most of his 80 years. He spent 18 months in an Indian prison in the 1990s, but recalls the simpler days of his youth.
“When I was a boy I went fishing with my father and there was no danger. After partition there was a wall created among people,” he said.
Until India and Pakistan reach a settlement, Dabla’s happy memories look likely to remain just that: memories.
