KADANOK, Russia (AP) - Russia's emergency chief says some of the devastating wildfires sweeping western provinces are out of control. And residents fear there are not enough firefighters to battle them.

The minister says tens of thousands of troops and volunteers are helping some 10,000 firefighters battle blazes in more than a dozen provinces. Seven of those provinces are under a state of emergency.

The official says firefighting efforts have saved more than 300 towns and villages from destruction, but he told President Dmitry Medvedev (dih-MEE'-tree med-VYEH'-dyev) that in some areas the fire is "getting out of control."

The fires have killed at least 40 people and destroyed almost 2,000 homes. They began after weeks of searing heat and almost no rain.

Temperatures in the Moscow area are expected to hit 100 this week.
