(CNN)Video footage from the Suez Canal shows the back of the Ever Given container ship, which has been stuck for almost a week, dislodged from the canal bank as salvage crews work to refloat the vessel.
However, it remains unclear if the front has been freed from its original stranded position. The video was sent to CNN from employees working on the rescue operation with the Suez Canal Authority (SCA).Ten tug boats are being used to pull the Ever Given from the front and back to try to free it, said the SCA in a statement. Crews from Egypt and around the world have been working nonstop to try to refloat the ship, but previous efforts have failed. This latest attempt, however, is being executed during high tide where the water in the channel is at its highest.

A massive effort to salvage the ship has focused on dredging sand from below the front and rear of the ship, before pulling the ship with tugboats. Read MoreRescue teams started digging deeper and closer to the ship on Sunday, with dredging reaching 18 meters (59 feet) at the front of the ship, the SCA said in a statement. Over 27,000 cubic meters (953,000 cubic feet) of sand has been removed so far, said SCA head Osama Rabie. Their efforts haven’t succeeded in moving the ship much — but its rudders and propellers were freed on Friday, allowing for some movement.”We managed to move the ship from the bow side by 4 meters (13 feet), and likewise from the stern side,” Rabie said on Saturday. “The dredging operations led to the ship moving, albeit a slight move, but it is a positive development, because in the first two days the ship was not moving at all.”Rabie added that the reasons behind the accident remained unclear. “There are many factors or reasons, fast winds and the sandstorm could have been a reason but not the main reason — it could have been a technical mistake or human error,” he said. “There will be further investigations.”Concerns rose over the weekend about the impact of the blockage on global supply chains. The Suez Canal, one of the world’s busiest and most important waterways, is losing an estimated $14 million every day in transit fees, while billions of dollars of cargo is backlogged on over 350 ships currently awaiting passage.The effects of the crisis are already clear. Nearby Syria imposed fuel rationing on Sunday to safeguard dwindling oil supplies, after oil tankers were unable to make deliveries due to the blockage. Syrian authorities said the ration order was necessary to “guarantee the continued supply of basic services to Syrians such as bakeries, hospitals, water stations, communication centers, and other vital institutions.”
