A photo posted Tuesday showed the Taiwan-owned MV Ever Given, a 400-metre- (1,300-foot-)long and 59-metre wide vessel, lodged sideways and impeding all traffic across the waterway as excavation trucks struggled to dig it out.

"The container accidentally ran aground after a suspected gust of wind hit it," ship operator Evergreen Marine Corp told AFP.

"The company has urged the shipowner to report the cause of the incident and has been in discussions with relevant parties including the canal management authority to assist the ship as soon as possible."

Bloomberg reported it had caused a build-up of more than 100 ships seeking to transit the canal.

"There was a grounding incident", Alok Roy, fleet director of BSM Hong Kong, the Ever Given ship manager, told the news agency.

Instagram user Julianne Cona posted a photo of the grounded ship from the Maersk Denver, now also stuck behind the Ever Given.

"Ship in front of us ran aground while going through the canal and is now stuck sideways," she wrote. "Looks like we might be here for a little bit."

Shipping website Vessel Finder said the ship was bound for Rotterdam in the Netherlands, and it was unclear why the vessel had stopped moving.

"Tug boats are currently trying to re-float the vessel," Leth Agencies, which provides crossing services to clients using the canal, said on Twitter.

The Suez Canal, dug more than 150 years ago, is one of the world's most important trade routes, providing passage for 10 percent of all international maritime trade.

Nearly 19,000 ships passed through it last year carrying more than one billion tonnes of cargo, according to the Suez Canal Authority (SCA).

It has been a boon for Egypt's struggling economy in recent years, with the country earning $5.61 billion in revenues from the canal in 2020.

President Abdel Fattah al-Sisi unveiled plans in 2015 for an expansion designed to reduce waiting times and double the number of ships using the canal daily by 2023.

In February, Sisi ordered his cabinet to adopt a "flexible marketing policy" for the canal in order to cope with the economic downturn caused by the coronavirus pandemic.

Egyptian authorities are yet to comment on the tanker incident.
