Smoke from a number of wildfires in Canada has led to air quality warnings in the northeastern United States. Skies have been hazy, resulting in decreased visibility and colorful sunsets.

In Massachusetts, the Massachusetts Department of Environmental Protection issued a statewide air quality alert that will stay in effect from midnight to 11:59 p.m. Thursday, MassDEP said in an e-mail Wednesday night.

Take a look at some photos of the haze from the Boston area and beyond.
