Federal Protective Services determined that reports of gunshots
at the building "were unfounded," the EPA said on Twitter.
"There were no injuries and the building is secure," it added.
A row of police cars could be seen in the area, in a photo
posted online by Washington television station WJLA.
Washington police spokesman Officer Hugh Carew confirmed that
police officers responded to the scene.
"The floors where the shots were reported were cleared," said
EPA spokeswoman Liz Bowman.
