SUEZ, Egypt (AP) — Two additional tugboats deployed Sunday to Egypt’s Suez Canal to aid efforts to free a skyscraper-sized container ship wedged for days across the crucial waterway, even as major shippers increasingly divert their boats out of fear the vessel may take even longer to free.

The MV Ever Given, a Panama-flagged, Japanese-owned ship that carries cargo between Asia and Europe, got stuck Tuesday in a single-lane stretch of the canal. In the time since, authorities have been unable to unstick the vessel and traffic through the canal — valued at over $9 billion a day — has been halted, further disrupting a global shipping network already strained by the coronavirus pandemic.
