ISMAILIA, Egypt (AP) — Dredgers, tugboats and even a backhoe have failed to free a giant cargo ship wedged in Egypt’s Suez Canal as the number of stacked-up vessels unable to pass through the vital waterway climbed to 150 and losses to global shipping mounted. Even with the aid of high tides, authorities have been unable to push the Panama-flagged container vessel aside, and they are looking for new ideas to free it. The Japanese owner of the skyscraper-sized cargo ship has apologized for the incident. Canal service provider Leth Agencies says the backup affected ships needing to travel into the Mediterranean and the Red seas.
