A 100-foot yacht burned outside Marina del Rey's harbor on Wednesday evening. It was loaded with 1,000 rounds of unspent ammunition and fireworks, according to its owner.

Firefighters say that it's possible the fire was fueled by ammunition and fireworks that were being hauled on the yacht.

Approximately 4,000 gallons of deiseal fuel have leaked from the now sunken boat. There is no current threat to wildlife or the general public.
