New Delhi: As Partition tore through the subcontinent in 1947, millions were forced to flee across a newly drawn border amid communal violence, killings and looting, and it was against this backdrop that Pakistan founder Muhammad Ali Jinnah, after seeing streams of people fleeing across a divided Punjab, reportedly struck his forehead and asked in despair: "What have I done?"
The episode is recounted by journalist and author Kuldip Nayar in his autobiography "Beyond the Lines".
