Parts of central Chile have recently experienced unusually high temperatures and dry weather, sparking dozens of forest fires that have killed more than 100 people. Over the weekend, wildfires burned through several hillside neighborhoods in the city of Viña del Mar, destroying hundreds of homes. A state of emergency was declared by Chilean President Gabriel Boric, who also declared two days of national mourning, as firefighters work to contain the blazes and survivors return to their homes to recover what they can.
