WASHINGTON (AP) — The flags at the U.S. Capitol have been lowered to half-staff to honor the five service members killed in Chattanooga, Tennessee, last week.

Senate Majority Leader Mitch McConnell and House Speaker John Boehner said in a statement that as Congress returned to session on Tuesday, the flags were lowered for the Navy sailor and four Marines killed.

McConnell said America continues to mourn the men, and the thoughts of the Senate are with their families and loved ones as well as all service members who serve around the world.

The shooting occurred at two military facilities.
