White House on Lockdown After Nearby Vendor Explosion

The White House was put on lockdown Saturday morning after a nearby food vendor cart suffered a small explosion, causing a security sweep before President Barack Obama and his family were about to leave for Selma, Alabama, according to a White House pool report.

Photos posted on Twitter from Will Sweet show heavy smoke from one of the food locations in the 400 block of 15th Street, Northwest on Saturday morning.

D.C. fire officials said the fire was extinguished and one person was evaluated on the scene, but not transported to a hospital.

Secret Service spokesman Brian Leary told The Associated Press around the same time, a bomb-sniffing dog detected something on a vehicle nearby.
