The Biden administration has offered U.S. assistance to Egyptian officials as they attempt to free a massive container ship stuck in the Suez Canal amid fears in Washington about an uptick in energy prices.

The Ever Given remains wedged partially sideways inside the canal, which is one of the world’s most important waterways for the flow of goods. The ship has space for 20,000 metal containers, which tower over the Suez’s banks while workers and equipment appear in miniature around its hull.
