WWII fire-bombing of Tokyo by US remembered 70 years on

Seventy years ago on the night of 9-10 March, in the Japanese capital, 334 American B-29 bombers dropped thousands of tonnes of incendiary bombs on the city's crowded wooden neighbourhoods.

They started a fire storm that burned at over 1,000 degrees and killed more than 100,000 people.

It was an event that dwarfed even the atomic bombing of Hiroshima, yet it's been all but forgotten around the world - even in Japan.
