Efforts are continuing to refloat the Ever Given, a 400m-long (1,300ft) container ship which has been blocking the Suez Canal in Egypt since Tuesday.
Dredgers have been clearing sand and mud away from the bow of the vessel, while tugboats and the ship’s winches are being used in an attempt to move it.
On Thursday, the Ever Given’s owner, Japanese firm Shoei Kinsen, apologised for the effects the incident has had on traffic waiting to go through the canal.
It said it was doing its utmost, along with local authorities and the vessel’s operators, to resolve the problem, but warned that it was extremely difficult.
