ISMAILIA, Egypt (AP) — At least 150 vessels are waiting to use the Suez Canal after a skyscraper-sized cargo ship wedged across the vital waterway. That’s according to canal service provider Leth Agencies. It says the backup Thursday affected ships both needing to travel into the Mediterranean and the Red Seas. The Ever Given, a Panama-flagged ship that carries cargo between Asia and Europe, ran aground Tuesday in the narrow, man-made canal dividing continental Africa from the Sinai Peninsula. It remains unclear when the obstruction will be cleared. That’s further imperiled global shipping, which relies on the canal.
