ABC News’ Tahman Bradley Reports:

President Obama and the first lady this morning visited the section of Arlington National Cemetery where the U.S. service members who died in the wars in Iraq and Afghanistan are laid to rest to pay tribute to them.

The president and Michelle Obama made their way to section 60 of Arlington, where they met with a family visiting a grave and walked a row of grave sites hand in hand. They also took a few minutes to greet others at the cemetery, shaking hands and taking pictures.

Section 60, located in the southeast part of the cemetery, is the burial ground for military personnel killed in Iraq and Afghanistan. This was the president’s third visit to the section.

After the visit, president and first lady traveled to a Washington, D.C.-area service event. They will participate in a number of 9/11 memorials and tributes on Sunday.

The two wars launched by the United States after 9/11 have claimed the lives of 6,213 military personnel.
