President Obama on Monday said the deaths of 19 firefighters battling an Arizona blaze shows the need to reassess wildfire management policy.

“I think we are going to have to ask ourselves a set of broader questions about how we are handling increasingly deadly and difficult firefights,” Obama said Monday at a press conference in Tanzania.

“Wildfires have been continually escalating at higher and higher cost, and putting more and more pressure not only on the federal fire services but also on state and local fire services, and we are going to have to think about what more we can do on that front,” Obama said.

“But for now, I think what we are most concerned about are how painful these losses are,” added Obama, who is on an eight-day, multi-nation tour through Africa.
