'Heartbreaking:' Wildfires leave Los Angeles communities in ruins. See photos of the damage

It's all hands-on deck in Southern California, where deadly fires continue to burn due to a combination of high winds, low humidity and relentless drought conditions.

Since multiple fires ignited across various communities in Los Angeles County last week, tens of thousands were forced to evacuate, more than 12,000 homes were destroyed or damaged and at least 24 people have been killed.

Scores of firefighters, including hundreds of prison inmates, are working around the clock to extinguish the flames amid "particularly dangerous" weather conditions in northern Los Angeles County and Ventura County areas.

President Joe Biden announced on Friday that the federal government would cover 100% of the costs incurred by California wildfires for the next 180 days. Biden has also encouraged people impacted by the wildfires to apply for assistance through Federal Emergency Management Agency programs.

"That said, that was a heartbreaking weekend for a lot of people in Los Angeles," Biden said Tuesday. "Ash was raining down like snow. Homes burned to the ground − thousands of those homes are gone. And we learned we lost more of our fellow Americans."

According to Biden, it's going to "cost tens of billions of dollars" to get the City of Angels back to where it once was.

Below are photos that capture the aftermath of the blazes, which continue to burn.
