D.C. Mayor Muriel Bowser said some people may be missing following a three-story collapse at a Watergate complex parking garage Friday morning.
Two workers were injured in the collapse, which also crushed at least one vehicle. A D.C. firefighters' union called the incident a "pancake collapse."

News4's Mark Segraves reports that two construction workers feared missing were later accounted for. However, because it is a public garage, officials say that it was impossible to immediately know whether anyone else may have been inside.
Crews have not been able to get fully inside the collapsed structure due to possible instability. They are working to shore up the structure further before continuing the search for anyone who may be trapped inside. It may take until Saturday before the garage is stabilized.
Rescue teams are on the scene with dogs to search the rubble of the garage. The D.C. Fire & EMS Department's only search dog has been deployed to Nepal to help in the aftermath of the earthquake there. Montgomery County Fire & Rescue sent their dogs to aid at the Watergate.
Two construction workers were injured in the collapse, said a D.C. Fire spokesman. One worker's injury was minor. The condition of the other patient is unknown.
The area of the garage that collapsed was under construction at the time.
"I was installing a panel," worker Gabriel Gresczyk told NBC News, his voice still shaking. "I was looking out and I heard a rumble, and a 40-foot-by-40-foot section of earth just went down, hitting the floor below it, and then that floor went down."
"One of our guys had just come up from that area, using one of the restrooms down there," he said. "Thank God he's all right."
Gresczyk said he didn't know whether anyone was in the area at the time.
The Watergate complex has been evacuated. Residents and office workers were initially told the problem was a water main break. The hotel portion has been undergoing renovations, which were expected to be completed this summer.
"We saw smoke coming from where the hotel is being built," said resident Dave Lilling. "...We saw the construction workers leave very quickly, and then the smoke dissipated. There was an announcement on the loudspeaker system which said, 'Hey, there's been a water main break and some building issues in B3.' They advised everybody not to go down there."
Police and fire officials said they didn't know yet what caused the collapse.
