The cost of fighting a massive Gulf of Mexico oil spill is mounting rapidly for the global oil company that owns the well.
London-based BP PLC says it has spent $450 million since the spill started after an April 20 oil rig explosion.
That's up by $100 million from the last company update three days ago.
BP said in a filing Thursday to U.S. securities regulators that the cost for its response includes efforts to contain the crude, drilling a relief well, money it has given to Gulf Coast states, settlements and federal costs.
BP's chief operating officer Doug Suttles said Wednesday the price tag increases at least $10 million a day. BP did not immediately respond to a message Thursday to clarify details of the new total.
