A skyscraper-sized container ship is blocking one of the world's busiest trade routes.

The Ever Given ran aground yesterday, and has become wedged across Egypt’s Suez Canal.

Dozens of vessels are waiting for rescue boats to free the 400m-long ship, which was knocked off course by strong winds.

About 12 per cent of global trade passes through the Suez Canal, which is the shortest sea link between Asia and Europe.

The operation to re-float the ship could take two days, and may cause major delays in global shipping.
