WASHINGTON—Some never-before-seen artifacts from the minutes following President John F. Kennedy's assassination are going on display in Washington.

The Newseum, a museum devoted to journalism, is marking the 50th anniversary of the assassination with exhibits and a new film about Kennedy. One exhibit, entitled "Three Shots Were Fired," follows the events that unfolded after Kennedy was shot in Dallas on Nov. 22, 1963. It opens Friday.

For the first time, the museum is showing items from assassin Lee Harvey Oswald at the time of his arrest. The display includes Oswald's clothing, wallet and a blanket used to hide his rifle in a friend's garage.

More than 100 rarely seen objects will be on display, including the 8 mm movie camera that captured the assassination on film.
