Engineers on Monday “partially re-floated” the colossal container ship that continues to block traffic through the Suez Canal, authorities said, without providing further details about when the vessel would be set free. 

Satellite data from MarineTraffic.com showed that the ship’s bulbous bow, once lodged deep in the canal’s eastern bank, had been partly wrested from the shore, although it remained stuck at the canal’s edge. The ship’s stern had swung around and was now in the middle of the waterway, tracking data showed. Although the development marked the vessel’s most significant movement since getting stuck last week, the salvage crew urged caution as obstacles loomed.
