The Coast Guard Is Blocking DC River Traffic As Police Search For 2 Potential Navy Yard Shooters

In response to a mass shooting at the Navy Yard in Washington, D.C. this morning, the Coast Guard has established a "temporary safety and security zone," blocking traffic on the Anacostia River.

Several people have been killed and others wounded. Police say one shooter is dead, and they are searching for two other potential shooters.

The zone stretches from the John Philip Sousa Bridge to Hains Point, where the Anacostia meets the Potomac River. The Navy Yard is about halfway between the two.

The zone will be in effect for "an undetermined amount of time," according to a Coast Guard press release.

Here's the map of the security zone. The Navy Yard is circled:
