"'Are you all right, mate?'" - Compassion: Why terrorism won't succeed

The Guardian reports from one of yesterday's eyewitnesses:

"Business analyst Abisha Moyo told the Daily Mail he heard a bang like a 'pistol going off' and saw a fellow tube passenger lying on the floor of their carriage.

He approached him and asked 'are you all right, mate?' but was then stunned to see the man was lying on top of a rucksack with smoke coming out. The suspect then calmly left the rucksack behind, jumped on the tracks and walked away down the line, said Mr Moyo."
