The latest attempt to stop the Gulf of Mexico oil leak has failed, the oil giant BP has said.
BP chief operating officer Doug Suttles said the firm was now shifting to a new strategy to stop the spill.
In the failed procedure - known as "top kill" - the firm had been blasting waste material and heavy mud into a ruptured well.
US President Barack Obama said the continued flow of oil was "as enraging as it is heartbreaking".
