A month after a wildfire erupted at the edge of the Grand Canyon, US firefighters were struggling Monday to bring the blaze under control.The level of containment -- the amount of the perimeter where firefighters have completely stopped the fire's progress -- stood at 13 percent on Monday.

The Dragon Bravo Fire exploded in size along the Grand Canyon’s North Rim this week as heat and strong winds drove the growth.

The Dragon Bravo Fire already destroyed the historic Grand Canyon Lodge inside the famed national park and about 100 other buildings.

The blaze injured three people, put hundreds under evacuation orders and threatened 460 structures, officials said.
