Fire experts and officials are warning that an intense wildfire could reach a town in western Canada this week. There are forecasts of strong winds that have fueled the out-of-control blaze approaching Fort Nelson in British Columbia. Thousands of people have evacuated. A local official said Monday that emergency crews are preparing for a “last stand” as dozens of remaining residents are urged to leave. The blaze is one of several out-of-control wildfires in western Canada threatening communities in provinces such as Alberta and Manitoba. Drought has made the fires worse.

Ukrainian officials and commanders say Russian troops are locked in intense battles with Ukrainian soldiers in the embattled town of Vovchansk and are pushing ahead with a ground offensive that opened a new front to put pressure on overstretched Ukrainian forces.  Moscow’s renewed northeast offensive, launched late last week, is the most significant border incursion since the full-scale invasion began. By Monday, only 200 to 300 residents remained inside Vovchansk, said Kharkiv Gov. Oleh Syniehubov, as Russian forces closed in from three sides. By intensifying offensive operations, Russia seeks to stretch Ukraine’s forces thin and forge breakthroughs ahead of the arrival of much-needed new munitions from the U.S.  and European allies, not expected to reach the battlefield for two months.
