Baltimore sues owner and manager of 'unseaworthy' Dali over bridge collapse

Baltimore has sued the operators of the container ship that hit and destroyed one of the US city's main bridges last month, killing six people.

The city says the Dali was "clearly unseaworthy" and accuses its owners and manager of negligence.

The ship's Singapore-based owner and manager have already asked a court to limit their liability.

The region is reeling from the closure of its busiest maritime transit port after the span collapsed on 26 March.

"None of this should have happened," attorneys representing the Baltimore mayor and city council argued in a federal lawsuit.

The city is asking the US District Court of Maryland for a jury trial to hold the defendants fully liable.
