A Democratic source familiar with the planning says Sen. Edward M. Kennedy is to lie in repose at the John F. Kennedy Presidential Library and Museum in Boston before his funeral at a city church.

Kennedy will be buried at Arlington National Cemetery near his slain brothers, another official knowledgeable about the arrangements told The Associated Press.

The Democratic source, who spoke on the condition of anonymity because of the sensitive nature of the planning, said Wednesday details are still being determined by the Kennedy family.

The funeral Mass will be at Our Lady of Perpetual Help Basilica, known as the Mission Church, in the Mission Hill neighborhood of Boston. Kennedy prayed there daily while his daughter, Kara, successfully battled her own cancer.
