LISBON, Portugal (AP) — Firefighters in Portugal say they are close to bringing under control a major wildfire that killed 64 people in the central area of the country.

More than 1,000 firefighters and nine water-dropping aircraft are battling the blaze in Pedrogao Grande, which is raging for a third consecutive day.

The Civil Protection Agency says it hopes to contain the flames Tuesday, though temperatures forecast to reach 43 degrees Celsius (109 Fahrenheit) and gusting winds remain a threat.

The death toll was raised from 63 to 64 late Monday.

Government officials say Prime Minister Antonio Costa has ordered an investigation into what happened on Saturday night, when the deaths occurred.
