The twilight zone: The aftermath of the Oklahoma tornado

Illuminated by evening light, a child's bed complete with cuddly toys sits in what remains of a family home, destroyed by the tornado which ripped through Moore in Oklahoma on 20 May, killing at least 24 people.

President Barack Obama, who visited the devastated town at the weekend to console those who had lost loved ones and property, promised that the government would be behind them "every step of the way" during efforts to rebuild.

The tornado was the strongest the US had seen for almost two years. It cut a path of destruction 17 miles (27 km) long and 1.3 (2 km) miles wide.
