An oil tanker has run aground at a port in Alaska, the US Coast Guard says.
The Seabulk Pride broke free from moorings while being loaded in Nikiski, south-west of Anchorage, and ran aground on silt.
The double-hulled tanker was carrying more than 100,000 barrels of different oil products. There were no immediate reports of any leak.
A spillage from the Exxon Valdez in Alaska in 1989 devastated wildlife and took four years to clean up.
