VENICE, La. — As Louisiana state and local officials continue to hammer BP and the federal agencies responding to the Gulf of Mexico oil spill, repeatedly threatening to “take matters into our own hands” if the response falls short, BP said Monday morning that it was further delaying its next attempt to shut off the leak.

The oil company has been planning to attempt a procedure known as a top kill, in which heavy fluid would be pumped into the well. Doug Suttles, chief operating officer for exploration and production, said in an interview on NBC on Monday morning that the top kill would be attempted Wednesday morning. BP had previously said it hoped to execute the procedure on Tuesday.
