Former US first lady Rosalynn Carter buried in Georgia

Uniformed officers from local police and sheriff's departments silently lined a street on Wednesday in the tiny rural birthplace of former president Jimmy Carter and Rosalynn, his wife of 77 years.

A group of high school students and other residents of Plains, home to a few hundred people, waved small US flags as the funeral cortege left the Maranatha Baptist Church for an interment at the Carter residence.

Residents of the town, adorned with murals of Jimmy Carter and other tributes to its most famous son, recalled Rosalynn as a humble neighbour who helped mow the lawns and organise the food bank at the Carters' church.

"They were down to earth people that could really spend time with anyone from whatever background and make you feel comfortable, make you feel loved," said Bren Dubay, a friend of the Carters and director of the nearby Koinonia Farm, a Christian charity that provides food and shelter.

Dubay joined others along the cortege route, holding pictures of the presidential couple and signs that read: "God bless you, Mrs. Carter."

On Monday, Rosalynn Carter lay in repose at the Jimmy Carter Presidential Library and Museum in Atlanta. On Tuesday, her 99-year-old husband made a rare public appearance since entering hospice care to attend a tribute service in Atlanta, joined by President Joe Biden and his wife, Jill Biden, four former first ladies and former president Bill Clinton.

During that service, mourners recalled Rosalynn Carter's prominent role during her husband's 1977-1981 presidency, in which she became a champion of mental health services, and the humanitarian work the Carters devoted themselves to after leaving the White House.

The couple worked to eliminate Guinea worm disease from West Africa and build affordable homes through the non-profit Habitat for Humanity. She took a special interest in protecting the degraded habitat of the monarch butterfly.
