An attempt Friday to refloat a giant container ship blocking Egypt's Suez Canal has failed, the vessel's managers said. "Another attempt to refloat the vessel earlier today... was not successful," the Singapore-based Bernhard Schulte Shipmanagement said in a statement, referring to the MV Ever Given, which has been wedged diagonally across the entire canal since Tuesday, shutting the waterway in both directions. bur-bfi/lg/dv
