[HIGHLIGHTS] The Baltimore Bridge Collapse: What is Known and What Are the Unknowns?

Sonar images detected several cars under the icy waters of the river. There is no indication that this was intentional.

At least seven people remain missing, two have been rescued and rescue teams are working against the clock in search of possible survivors. The port of Baltimore, one of the largest and busiest on the planet, was closed until further notice, but loading and unloading trucks remain operational. US President Joe Biden was informed of the collapse and is coordinating with Maryland state authorities and federal agencies.
