The horror of it all is almost unimaginable.
Over 300 workers burned and suffocated to death in their workplaces, a garment factory and a shoe factory.
Some died while trying to jump out of windows to safety.
There were no emergency exits, no escape routes.
Not in Victorian England in the 19th century. Not in New York City a century ago.
But this week, in the second decade of the twenty-first century.
They died in Karachi and in Lahore, making the garments and shoes that you may be wearing right now.
We honour the memory of those lives cut short by demanding justice --
- an impartial inquiry into what happened - and punishing those at fault;
- compensation for the families of those killed and injured;
- and an investigation into the failures of those public authorities who should have been there to ensure the workers' safety.
The unions in Pakistan are asking us all to take a minute and send off our messages of protest to the Prime Minister.
