MONTREAL, Canada: The largest town in Quebec's north was being evacuated on Tuesday as firefighters worked to beat back threats from out-of-control blazes in remote communities in the eastern Canadian province's northern and northwestern parts.

Quebec's forest fire prevention agency said more than 150 forest fires were burning in the province on Tuesday, including more than 110 deemed out of control. The intense blazes are blanketing the northeastern United States and parts of eastern Canada in a haze, turning the air acrid, the sky yellowish gray and prompting warnings for vulnerable populations to stay inside.
