A large backlog of ships has been building at both ends of the Suez Canal since Tuesday after an Evergreen Marine-controlled containership got stranded in the Egyptian waterway's southern section.

Gulf Agency Co (GAC) said the 20,388-teu Ever Given (built 2018) ran aground around the 151 km mark in the canal on Tuesday morning and has been blocking all traffic.

As of noon local time (10:00 GMT) on Wednesday, the vessel was partially refloated and sat alongside the canal bank.
