Solemn ceremony to mark JFK killing
Loose gatherings of the curious and conspiracy-minded at Dallas' Dealey Plaza have marked past anniversaries of the assassination of President John F Kennedy.
But for the 50th anniversary tomorrow, the city of Dallas has planned a solemn ceremony in the plaza he was passing through when shots rang out. There will be brief remarks by the mayor and the tolling of church bells.
It's an approach that will be mirrored in Boston, where the JFK Library and Museum will open a small exhibit of never-before-displayed items from Kennedy's state funeral and host a musical tribute.
And in Washington, President Barack Obama will meet privately at the White House with leaders and volunteers from the Kennedy-established Peace Corps programme.
