Chileans mourn wildfire victims

People across Chile have observed two days of national mourning following a string of deadly wildfires. Officials say that as of Wednesday, the disaster has killed at least 131 people and left hundreds of others missing.

The fires broke out on Friday in the Valparaiso region. Thousands of homes and other buildings were destroyed. The UN says it was the deadliest wildfire in Chile's history.

Investigators are looking into what sparked the fires and whether someone might have started one deliberately. They believe the first ignited near the coast, then spread through towns and villages in the mountains.

One resident said there was a lot of wind and that they saw "big balls of fire" fly by.

Chile was already dealing with severe heat and drought brought on by the weather pattern known as El Nino.

Raul Cordero, a climatologist at Universidad de Santiago de Chile, said climate change played a big part in how quickly the flames spread and how far. He added that when winds are so intense and temperatures are so high, there is "no way" to stop such fires from spreading.

He also warned that most communities do not have the resources to prevent such disasters from happening again.
