[Updated at 11:30 a.m. ET] BP, Transocean and Halliburton all share responsibility for the deadly explosion that resulted in the April 2010 Gulf of Mexico oil spill, according to the final federal report on the matter released Wednesday.
The three companies "violated a number of federal offshore safety regulations," according to the report, which includes a series of recommendations for improving drilling safety.
An explosion on the Deepwater Horizon rig led to more than 200 million gallons of oil being released into the Gulf. Eleven people working on the rig died in the explosion, while 16 others were injured.
Besides the oil, hundreds of thousands of gallons of chemical dispersant went into the water. At the peak of the crisis, in June 2010, 37% of Gulf waters - a total of 88,522 square miles - were closed to fishing due to contamination.FULL STORY
