加拿大扑救山火行动出现转机

Canadian officials say they have reached a turning point in combating the huge wildfire that has destroyed a large area of the province of Alberta in western Canada.

Cooler temperatures and light rain in the region have made for "great firefighting weather," said Chad Morrison, an Alberta fire official. "We can really get in there and really get a handle on this fire and really get a death grip on it."

While the flames so far have not reached any major oil processing facilities, they remain closed and global oil prices have soared over concerns about the Canadian fires.

It is not immediately clear when processing facilities will open. Many oil workers have been evacuated and are camped out with their families.

Experts estimate oil production will be shut down for at least two or three weeks.

Alberta is home to the world's third-largest oil reserves, behind Saudi Arabia and Venezuela.
