Flags at half-mast in Washington DC following Vegas shooting

The U.S. Capitol dome backdrops a column of American flags standing at half-staff as the sun rises on Tuesday, Oct. 3, 2017, at the foot of the Washington Monument on the National Mall in Washington. President Donald Trump ordered flags to be flown at half-staff at the White House and upon all public buildings and grounds, at all military posts and naval stations, and on all naval vessels of the Federal Government in the District of Columbia and throughout the United States and its Territories and possessions until sunset on October 6, 2017, to pay respect for the victims of the shooting at a country music concert Sunday night in Las Vegas.
