By TAMMY WEBBER and JIM MORRIS (Associated Press) VANCOUVER, British Columbia (AP) — Residents heeded warnings to evacuate the capital of Canada’s Northwest Territories as a wildfire burned toward the city of 20,000, while firefighters on Friday battled a growing fire that set homes ablaze in a city in British Columbia. Thousands of people in Yellowknife drove hundreds of kilometers (miles) to safety, with authorities guiding motorists through fire zones, or waited in long lines lines for emergency flights as the worst fire season on record in Canada showed no signs of easing. Airtankers flew missions overnight to keep the only route out of Yellowknife open.
