A state of emergency has been declared in the province of Alberta in Canada after a wildfire forced all 88,000 residents of Fort McMurray to flee.
Officials say the fast-moving blaze could destroy much of the city.
The fire, which broke out on Sunday in the heart on the country's oil sands region, has gutted 1,600 buildings, including a new school.
The evacuation was the largest-ever in Alberta. Oil companies operating in the area have been forced to cut output.
Several firms have shut down some pipelines. This was done to help evacuate non-essential personnel, reports say, but oil facilities are not in the current path of the fire.
So far there have been no reports of deaths or injuries, but two women gave birth in one evacuation center, foreign media reports.
