Baltimore bridge crash causes supply chain concerns

Concerns have been raised of a "ripple effect" on global supply chains after a container ship crashed into a bridge in the US city of Baltimore.

The ship, named the Dali, hit a support column of the Francis Scott Key Bridge in the early hours of Tuesday morning, causing it to collapse.

Six people are missing presumed dead. read more
