BUENOS AIRES, Argentina — Ash from a Chilean volcano fell across a wide swath of South America on Thursday, forcing cancellation of most flights across the southern half of the continent and grounding the presidents of Argentina and Uruguay.
The ash dusted streets in the Uruguayan capital of Montevideo as well as Argentina's Buenos Aires, roughly 850 miles northeast of the Cordon Caulle volcano that began erupting on Saturday.
Even Argentine President Cristina Fernandez was forced to use a car rather than a helicopter to get to work on Thursday. Her planned meeting with Uruguayan leader Jose Mujica was scrapped because he was unable to fly to Buenos Aires.
Wildfires threaten huge areas in Russia

MOSCOW — A devastating wave of wildfires across Russia could ravage millions of acres of forests and cause worse damage than last year's catastrophic blazes, environmentalists and officials said Thursday.
"We're burning, burning badly," Greenpeace's forestry expert, Alexey Yaroshenko, said. In 2010, an unprecedented heat wave triggered fires that killed 55 people, destroyed thousands of houses and torched 6.4 million acres of forests — an area slightly larger than Oregon.
