An explosion and fire at a commercial building in downtown Los Angeles Saturday night has wounded 11 firefighters, the LA Fire Department said in a statement. AP describes the business as a "hash oil manufacturer."

Why it matters: The LAFD said the business, Smoke Tokes Wholesale Distributor, is "reportedly a supplier for those who make butane honey oil. The cause is of great concern to us and is under active investigation." More than 230 firefighters responded following a "mayday" distress call, the department tweeted.

A tweet previously embedded here has been deleted or was tweeted from an account that has been suspended or deleted.

Of note: Per AP, butane is an "odorless gas that easily ignites, and it’s used in the process to extract the high-inducing chemical THC from cannabis to create a highly potent concentrate also known as hash oil. The oil is used in vape pens, edibles, waxes and other products."

The big picture: The fire department said the severity of injuries was not confirmed. But Mayor Eric Garcetti tweeted that all of the firefighters were being "treated for their injuries and in stable condition."

  • The LA Fire Department said in its statement that firefighters were attending the fire call-out "when a significant explosion occurred."
  • A mayday call was put out over the radio and additional units attended the Major Emergency incident.
  • SmokeTokes website says it is an "international distributor and wholesaler of smoking and vaping products, and related accessories," selling products including torches and butane, vaporizers and pipes.

Editor's note: This article has been updated with new details throughout.

Los Angeles Mayor Eric Garcetti announced Wednesday he's authorized the city's Department of Water and Power (DWP) to shut down utilities at locations that host large gatherings during the coronavirus pandemic.

Driving the news: Garcetti's announcement follows a fatal shooting at a house party attended by roughly 200 people last Monday, the Los Angeles Times notes.

Pfizer says COVID vaccine over 90% effective in kids

Pfizer and BioNTech said their COVID-19 vaccine was more than 90% effective at protecting children between the ages of 5 and 11 from symptomatic infections from the virus, according to a study posted online by the Food and Drug Administration Friday.

Why it matters: Pfizer is seeking an emergency use authorization to vaccinate children — one of the last groups of Americans still largely ineligible to receive a coronavirus vaccine.

Changing the inflation conversation

Inflation looks like it’ll run hot for longer than plenty of smart people thought it would. The conversation over just how much more Americans will have to pay for their stuff has taken on a new intensity, as supply problems show few signs of fading.

Why it matters: The rate of price growth has remained consistently strong in recent months — a time that some thought would bring cooling prices after an initial reopening spike. What goes on with prices will influence the decisions made by Congress, the Biden Administration, and the Federal Reserve.
