Police in Saskatoon had to close off a Riversdale neighbourhood street this afternoon after a house fire filled the area with dense smoke.

The fire happened at about noon on the 600 block of Avenue H S.

Fire crews on one side of the house used a fan to clear away smoke, while crews on the other side broke windows and popped off security bars with chainsaws.

The cause of the fire is still unknown, but damage is estimated to be about $200,000.
