A wildfire out of control in Alberta, Canada could burn for months, officials say.
The fire has already burned large parts of the Canadian oil sands town of Fort McMurray and there is fear it could double in size and reach a major oil sands mine and even the neighbouring province of Saskatchewan.
The blaze is expected to have consumed more than 200,000 hectares by Sunday, the Alberta government says, and is expected to continue to grow because of high temperatures and winds as well as dry conditions.
Significant rainfall is needed to stem the tide of the fire.
Meanwhile thousands of people continue to be evacuated including work camps north of Fort McMurray on Saturday. As well, thousands of displaced residents got a drive-by view of some of the destruction in the town.
