San Bruno Fire Leaves 6 Dead (HORRIFIC PHOTOS)

Firefighters poured water on flaming and smoldering wreckage early Friday after a massive explosion sent blazes roaring through a neighborhood in the hills south of San Francisco, killing at least one person, destroying more than 50 homes and damaging dozens of others.

Thursday night's explosion shot a fireball more than 1,000 feet in the air and sent frightened residents fleeing for safety and rushing to get belongings out of burning homes, witnesses said.
