Russians fought a fire near the village of Golovanovo, in the Ryazan region of Russia on Thursday
The move was the latest of several abrupt interventions in the Russian economy by Mr. Putin, who called the ban necessary to curb rising food prices in the country. Russia is suffering from the worst heat wave since record-keeping began here more than 130 years ago.
“We need to prevent a rise in domestic food prices, we need to preserve the number of cattle and build up reserves for next year,” Mr. Putin said in a meeting broadcast on television. “As the saying goes, reserves don’t make your pocket heavy.”
Prime Minister Vladimir V. Putin on Thursday banned all exports of grain after millions of acres of Russian wheat withered in a severe drought, driving up prices around the world and pushing them to their highest level in two years in the United States.
