saw blade got stuck in a riser pipe in its latest attempt to contain the spill.

BP is currently trying to free the blade, which was trying to cut through the well head so a cap can be attached to stem the flow of oil that has been spilling into the gulf.

The oil giant also confirmed its "top kill" attempt proved unsuccessful, potentially due to a malfunctioning disk inside the well about 1,000 feet below the ocean floor.
