NO SMOKE WITHOUT FIRE

I took this picture 11 days ago from the balcony on my condo. At the time is looked pretty dramatic, especially when accompanied by at least a dozen fire trucks of all shapes and sizes racing along the highway.
Tanya heard people talking that the smoke was coming from a shopping centre at Bang Kae which is about five miles away, but I've not been able to find out anything else.
One thing's for sure - it was more than someone ordering a well-done steak from Sizzlers Restaurant.
