MOORE, Okla. - A monstrous tornado as much as a mile wide roared through the Oklahoma City suburbs Monday, flattening entire neighborhoods, setting buildings on fire and landing a direct blow on an elementary school.

Volunteers and first responders were searching through debris looking for survivors.

Oklahoma City Police Capt. Dexter Nelson said downed power lines and open gas lines posed a risk in the aftermath of the system.

SOCHI, Russia - The mountains of Sochi are now home to Potanin's slope, Gazprom's gondola lift and Sberbank's ski jump.

In contrast, the much-larger 2012 Summer Olympics in London cost about $14.3 billion and the 2008 Summer Games in Beijing cost about $40 billion.

For President Vladimir Putin, the games have been a matter of pride.
