The collapse of Baltimore’s Francis Scott Key Bridge is a “global crisis”, says Maryland Governor Wes Moore.

“The national economy and the world’s economy depends on the port of Baltimore,” Mr Moore said during a media conference on Thursday.

“The port handles more cars and more farm equipment than any other port in the country.

“Last year alone, the port handled $80 billion of foreign cargo – the largest in the country.

“The last 24 hours that we have had a chance to work with the navy to mobilise major resources all around to be able to make sure that we are getting things moving, and this has happened at record speed.”
