A White House commission investigating the oil spill in the Gulf of Mexico has said the companies involved were more interested in saving money than saving lives. It says the April explosion at the Deepwater Horizon oil rig was the result of failures by BP, Halliburton, Transocean and government offices dealing with the well. The commission also said similar accidents could happen again if the industry does not change the way it operates. Al Jazeera's John Terrett reports from Washington.
