Apple will be donating to Notre Dame rebuilding efforts to help restore the historic cathedral in Paris, according to a tweet from its CEO Tim Cook. 

Notre Dame was significantly damaged in a fire on Monday. While the cause of the blaze remains unknown, the cathedral had been undergoing renovations, and at this point, it is believed that it may have been accidental. Fortunately, reports indicate that no lives were lost in the fire, but at least one first responder is injured. 

Cook did not indicate how much Apple will donate to the efforts. Less than 24 hours after the fire, French billionaires and other companies have already pledged over $450 million to help rebuild Notre Dame.
