The head of BP, Tony Hayward, has faced a barrage of tough questions from members of the US congress over his company's handling of the Gulf of Mexico oil spill.
Politicians accused the energy giant of cutting corners and ignoring warnings, paving the way for the worst oil spill in US history.
Tony Hayward said it was too early to know what caused the incident and offered an apology for what happened.
