BIRMINGHAM, Ala., Aug 13 (Reuters) - Alabama is suing BP Plc BP.LBP.N and Transocean RIG.N for damages sustained from the Gulf of Mexico oil spill, the state's attorney general said on Friday.

“We are making this claim because we believe that BP has inflicted catastrophic harm on the state,” attorney general Troy King told Reuters.

“We are suing them for the amount it will take to make Alabama whole,” he said, declining to name a figure. (Reporting by Matthew Bigg, editing by Pascal Fletcher and Jackie Frank)
