The Canadian fire marshall with the MIF-H explains to the MIF-H police liaison officer, CDR Brad Steele (USN) what the Haitian firemen are doing. Which a fresh load of water for their trucks, and the doors pulled off a few buildings, they are sending an attack team ahead of the fire to keep it contained. I would be in no hurry to go into a burning buildin with no breathing gear after having been up all night - but that is exactly what they did.
The wind is blowing the fire towards the market in the background. The market is even more full of flammable materials than the street.
